 Radians QuestionMessage #1 Posted by Vincze on 15 Aug 2007, 9:59 a.m. Have a question. If I take the Lat and Long of let's say LAX Airport(33deg 57min N, 118deg 24min w) enter into 35s and convert to RAD I get following.```33.57 ->RAD Answer = .585907 ``` But if use longer manual formula of `(LatDeg + LanMin/60)*PI/180 ` I get:`(33+57/60)*pi/180 = .592539` Why are these not the same? I know the manual calculation is correct, so I am figuring that I am doing something wrong with the calculator. This seem only like small issue, but this translate into bigger issue when run through calculations that I need to do.

 Re: Radians QuestionMessage #2 Posted by Dave Johnson on 15 Aug 2007, 10:22 a.m.,in response to message #1 by Vincze 33.57 = 33 degrees and 34.2 minutes 33.57 *pi/180 = .585907

 Re: Radians QuestionMessage #3 Posted by Vincze on 15 Aug 2007, 11:18 a.m.,in response to message #2 by Dave Johnson Okay, maybe I am entering information wrong. How should I enter 33deg 57 minutes N? I thought it would be 33.57

 Re: Radians QuestionMessage #4 Posted by Vincze on 15 Aug 2007, 11:23 a.m.,in response to message #3 by Vincze Never mind, I figure out... ```33.57 HMS -> ->RAD Answer = .592539 ``` Stupid Hungarian me.

 OT: Labels (non-calculator)Message #6 Posted by Ed Look on 15 Aug 2007, 12:19 p.m.,in response to message #4 by Vincze Vincze, since you insist on using that label, I'll mention that there used to be a baseball player, a pitcher, Al Hrabosky, who called himself "The Mad Hungarian", in an effort to strike fear into opposing hitters. When he was younger and pretty good, he didn't need nor have the nickname. When he was older and less able, the "scary" name didn't help. But many fans remember him as The Mad Hungarian.

 SIN on 35s not same as SIN in ExcelMessage #8 Posted by Vincze on 15 Aug 2007, 1:36 p.m.,in response to message #7 by Vincze Here a funny thing. I do find sin of say 100 on hp35s and I get .984808, but in MS excel, it come out as -.50637. Is something different in Excel?

 Re: SIN on 35s not same as SIN in ExcelMessage #9 Posted by Les Wright on 15 Aug 2007, 1:42 p.m.,in response to message #8 by Vincze the Excel worksheet function expects the argument to be in radians. change your 35s to radians mode and check! Les

 Re: SIN on 35s not same as SIN in ExcelMessage #10 Posted by Vincze on 15 Aug 2007, 1:57 p.m.,in response to message #9 by Les Wright What if I already convert to radians though? Meaning: ```33.57 HMS -> ->rad sin ANSWER = .010342 ``` but Excel show .558469 If I take .010342 and ->rad I get .000180, which still wrong.

Meaning: ```33.57 HMS -> ->rad sin ANSWER = .010342 ``` You are taking the sine of an angle in radians but your calculator is still in Degree mode. If you want the right answer with the keystrokes you have, put your calculator in Radians mode first--MODE 2 on the 35s. You get the right answer like magic. Les Edited: 15 Aug 2007, 2:11 p.m.

 Re: SIN on 35s not same as SIN in ExcelMessage #12 Posted by Vincze on 15 Aug 2007, 2:39 p.m.,in response to message #11 by Les Wright I try it that way, but final outcome is not correct still. Let me illustrate what I have in Excel.```VARS: LAT1 // Latitude 1 LON1 // Longitude 1 LAT2 // Latitude 2 LON2 // Longitude 2 =ACOS(SIN(Lat1)*sin(Lat2)+COS(Lat1)*Cos(Lat2)*Cos(Lon2 - Lon1)) ``` All Latx and Lonx use (Deg+Min/60)*pi/18 so if: [pre] Lat1 = 33 deg 57 min = 0.592539281 Lon1 = 118 deg 24 min = 2.066469834 Lat2 = 40 deg 38 min = 0.709185453 Lon2 = 73 deg 47 min = 1.2877621 /[pre] Based on this, Excel calculate 0.623584645 Radians I guess where I confused is I believe I need to convert all Lat and Lon from HMS to decimal (HMS->), yes? And then I thought to Radians with ->RAD. When I try in RAD mode, and just convert from HMS and not also to RAD, I still get wrong answer. I hope it just me not knowing how to use 35s, and me not be dummy about this.

 Re: SIN on 35s not same as SIN in ExcelMessage #14 Posted by Les Wright on 15 Aug 2007, 2:55 p.m.,in response to message #12 by Vincze Listen, I don't know exactly what you are trying to do, but this seems to be an angular mode issue. One thing you need to know is that Excel trig functions accept radians as arguments, and the arc trig functions return radians. No exception. If you want to get the same results on your 35S, you have to make sure the MODE is set to RAD and that all of your angles are converted first to radians in both Excel and the calculator. Am I missing something here? I think you believe there is a serious bug in the 35s trigonometrics. Apart from the cosine bug near 90 degrees, I don't think there are. I think you are simply getting bogged down in going back and forth between radians and degrees. This is, respectfully, a high school math issue, not a calculator or Excel issue. Sort that out and all of your results should fall into place.

 Re: SIN on 35s not same as SIN in ExcelMessage #15 Posted by Vincze on 15 Aug 2007, 3:18 p.m.,in response to message #14 by Les Wright No, I know problem not with calculator, but with me.

I have bolded your error. Of course you have to convert your angles to radians if you are in radians mode. I don't think the 35s is different from any other HP in this regard. Les

 Re: SIN on 35s not same as SIN in ExcelMessage #17 Posted by Les Wright on 15 Aug 2007, 3:12 p.m.,in response to message #12 by Vincze Here is my final hint, and then I am going to let you wrestle with this yourself: ```1. Put the calculator in radians mode 2. Enter LAT1 3. Convert it to decimal mode via HMS-> 4. Convert those degrees via ->RAD 5. Store it in a variable or write down the result (which is LAT1) in radians. 6. Repeat 2 thru 5 for each of LAT2, LON1, LON2 7. Compute your desired angle with your formula. It is in radians, and should agree with Excel 8. If you want to see the result in degrees, execute ->DEG ``` Alternately, you can keep the calculator in degree mode and skip steps 4 and 8 and you will get the result in degrees. For Excel to agree, compute everything in radians but change the result cell to =ACOS(SIN(Lat1)*sin(Lat2)+COS(Lat1)*Cos(Lat2)*Cos(Lon2 - Lon1))*180/PI Les Edited: 15 Aug 2007, 4:09 p.m.

 Re: SIN on 35s not same as SIN in ExcelMessage #19 Posted by Alain Mellan on 16 Aug 2007, 1:59 p.m.,in response to message #18 by Stefan Vorkoetter Quote: There's a difference between converting to radians, and being in radian mode. That's actually an interesting problem. Why is this acting diffently from the BIN/DEC/HEX mode? With these modes, it's changing the display of a number to a different base. Same thing, it's still the same complex number whether we are in x+iy or r,theta display. What if when we change mode, it does the DEG/RAD conversion? Would that be an improvement? Any thoughts?

 Re: SIN on 35s not same as SIN in ExcelMessage #20 Posted by Stefan Vorkoetter on 17 Aug 2007, 11:50 a.m.,in response to message #19 by Alain Mellan Because BIN/DEC/HEX mode and real vs. complex affect all numbers. Degrees vs. radians affects only angles. Consider calculating the value of 2+sin(45). You'd enter: ```2 ENTER^ 45 sin ``` The calculator should obviously not convert the 2, since it's not an angle. As for the 45, you might want the calculator to convert it from degrees to radians if you're in radian mode, but how is it supposed to know that you've entered it in degrees? Perhaps you meant 45 radians! Stefan

 ApologyMessage #21 Posted by Vincze on 16 Aug 2007, 9:31 a.m.,in response to message #1 by Vincze Someone send me e-mail telling me to stop posting such "ignorant" questions as I am dumbing down the group. I apologize for this, and that was not my intention. Because of this, I wish to apologize to group and let all know that I will not post any further questions unless they are considered "worthy", or unless I have "worthy" comment. I am very sorry, but I wish to thank all of you who help me yesterday and in previous days. I sometime get stuck with manual (I wish they had Hungarian version) as I am very old school with things, and I know that makes me a bit slower than many of you. Take care.

 Re: ApologyMessage #24 Posted by Vincze on 16 Aug 2007, 11:44 a.m.,in response to message #23 by Thor Lansen I no say who it is, as I not stoop to that level. I also know what happen to snitch in Hungary, and I not want to be considered snitch. Please know that it was not someone who posts answers to my question. It actually person who I never see before. I know I not stupid, because I very successful business person. I have acquired many things in United States. I know I post sometime stupid questions, but I not used to programming calculator, so I not understand results sometime. Anyhow, I go now so I not waste peoples time.

 Re: ApologyMessage #25 Posted by Ed Look on 16 Aug 2007, 11:54 a.m.,in response to message #24 by Vincze Hey Vincze, don't leave! And, don't apologize!! There have been one or two posters here over the years that have some rather... well, STRONG opinions and are not very polite about telling others. Believe me, over 99% of us don't mind your posts. In fact, some of them do make some of us think more. So, don't stop. Remember, your questions are from a thinking man about a bunch of basically well-thought out machines and how bad can that be, unless the critical person is so full of himself that he thinks he's smarter than most other posters here. In fact, including yourself, this is one of the most intelligent groups of people who informally chat on the Internet on a prolonged basis! Forget about the stupid jerk who e-mailed you.

 Re: ApologyMessage #32 Posted by Chan Tran on 16 Aug 2007, 8:33 p.m.,in response to message #31 by bill platt Well can I ask a stupid question? I read but I am not sure that whether Sin(X) on the 35s and Sin(X) in Excell give the same result or not?

 Re: ApologyMessage #33 Posted by Vincze on 16 Aug 2007, 8:51 p.m.,in response to message #32 by Chan Tran Chan, my friend, I give short answer. Yes and No. :) If I put calculator in RAD mode, then I get same result in Excel. It appear Excel convert on the fly to Radians. I never knew this. It makes me wonder what high level programing languages do as well, as I have never really tested either, but I would think it would be same as Excel.

 Re: ApologyMessage #35 Posted by Vincze on 17 Aug 2007, 7:43 a.m.,in response to message #34 by Thomas Okken Quote: I think what got you confused was when you were trying to use the Great Circle Distance formula, where you actually have *two* conversions to worry about, namely the conversion between degrees-minutes-seconds (which is used in navigation) and decimal degrees, and then the conversion between decimal degrees and radians. As long as the calculator is in DEG mode, all you need to do is the H.MS -> H conversion before applying sin or cos; if the calculator is in RAD mode, you need to do H.MS -> H, and then DEG -> RAD, before applying sin or cos. Why, though, if you are in RAD mode, do you have to convert from DEG -> RAD? Is it because I am placing information that is in degrees? Meaning 35 degrees 24' 00"

 Re: ApologyMessage #39 Posted by Ed Look on 17 Aug 2007, 12:03 a.m.,in response to message #38 by Trent Moseley While we're still on the subject of apologies, I'd say the 35s is something HP shouldn't have to apologize for, either. I'd say they got it right for the most part (see threads about the checksum issue). It's very hard to be completely perfect.

 Re: ApologyMessage #40 Posted by Les Wright on 17 Aug 2007, 3:42 a.m.,in response to message #21 by Vincze I have to admit I was getting a little grouchy because your dilemma seemed so clear to me and I was at a loss at to try to explain it more clearly. Regrettably, I would not make a good high school math teacher. That said, I think you have the right and privilege to post whatever you like of even passing relevance to the aims of the Forum. If someone doesn't want to read your stuff, they don't have to. I have to scold you for this "stupid Hungarian" insult you heap on yourself whenever you bump up against something you don't know. I can't imagine it is a very pleasant experience to so harshly and inaccurately criticize yourself for something so human as not knowing everything. If I called myself a "moronic Canadian" everytime I bumped into something that stumped me, I would be so depressed from the self-abuse I wouldn't be able to get out of bed in the morning. Take care of yourself, and enjoy the 35s. Les

 Re: ApologyMessage #41 Posted by Vincze on 17 Aug 2007, 8:43 a.m.,in response to message #40 by Les Wright I not mind calling myself "stupid Hungarian". It my way of laughing at myself. It really no different than when I work on something and I struggle with it for hours and then finaly figure it out and say, "Vincze, you dumb a*s". Now if someone call me stupid Hungarian, yes that would hurt and diminish my self worth. I know I am only human, and I know that I not know everything, so until I know everything (which never will happen) I am a stupid Hungarian.

 Re: ApologyMessage #42 Posted by Juan J on 18 Aug 2007, 9:07 p.m.,in response to message #41 by Vincze Hello Vincze, Lanczos, Eotvos, Von Neumann, Eugene Wigner and Edward Teller, notable physicists and mathematicians, as well as my longtime friend Philip, who taught me a thing or two about computers and life, come to my mind when I think about Hungarians. Yours is a land of remarkable, if not gifted people, so there is no such thing as a stupid Hungarian who should not post here. You are anything but stupid, Vincze, and you should keep posting. For occasional posters like me in particular and all the other contributors in general it is good to read from people like you. However, in the 1950s there was a "theory," so to speak, circulating amongst the non-Hungarian colleagues of some of the people I mentioned above: Hungarians are from Mars. The reasons: 1. They are very smart. 2. The Hungarian language is different from all the other languages in Central Europe (and presumably on Earth.) 3. They are like gypsies (the reason why they came from Mars in the first place.) You can find the whole story in "The curve of Binding Energy", by Roger (or it was Richard?) McPhee. The point is, beyond saying "stupid Hungarian" as a way to express one's inability to grasp the obvious, ther is no such thing. Please keep posting and disregard the occasional idiot who e-mails you adivising otherwise. My two cents.

I think most ethnic people are like this. One thing about Hungarians, is they really like jokes. They also take very seriously math and science. You may or may not know that we invent BASIC language, the ballpoint pen, atom bomb, and other things. Granted, these were not all invented in Hungary, but by Hungarians. Also, most Hungarians are very giving. We give you shirt off our back if you need. Sometime people say this our downfall and we get taken advantage because of. With me, I don't see it that way. I rather give, and try and help person. Sure, someone may take advantage of me sometime, but most time, I helping someone and not take advantage of me. We also very proud of our food. It very bad manner if you offered food from Hungarian and you not take. Many time it best not to ask what is in food. ;)

Barbosa on 19 Aug 2007, 8:33 p.m.,in response to message #50 by Vincze Hello Vincze, From some of your previous post, it's clear that most of your problems stem from the fact that your handbooks are written in English, rather than Hungary. You're right, manuals written in a language not our own sometimes look Greek to us (I wonder how the Greek would say that :-) I hope the following expresses this feeling correctly :-) ``` Once there was a freak Who was always up the creek. Surely knowledge-hungry Was this guy from Hungary. But, alas, his books were 'n Greek! ``` Don't worry about the word freak. Once someone said we're all freaks here. My knowledge of English is not better than yours, but I think this shoudn't be considered offensive, quite the other way around.

 Re: Apology (edited to add missing part)Message #54 Posted by Vincze on 19 Aug 2007, 9:03 p.m.,in response to message #53 by Gerson W. Barbosa You know, I remember onetime being with Hungarian friend in America, and I overheard a couple who were Asian, talking their language, and I ask my friend, "I wonder if we sound as goofy to them as they sound to us?" It funny what we think is normal sounding and what not. Yes you are right, reading English is a bit challenging at times. I can talk it well, but writing and reading have always been hard for me. My wife keep asking me why I try and get MBA since I have done well in life, but I want American degree, not just MBA. I'm sure I could get MBA in Hungary very easily, but getting degree in USA very hard sometimes. Anyhow, thank you for kind words my friend.
