 HP Solve calculator newsletterMessage #1 Posted by Matt Kernal on 9 Dec 2008, 6:16 p.m. Forgive me if someone has already posted a link to these monthly pdf newsletters: HP Solve (December has some HHC2008 photos). Thanks HP. Matt Edited: 9 Dec 2008, 6:34 p.m.

 Re: HP Solve calculator newsletterMessage #2 Posted by Bruce Bergman on 10 Dec 2008, 12:49 a.m.,in response to message #1 by Matt Kernal If you want an example of something that HP is doing RIGHT, and a direction they're heading that's really spot on, it's the new Solve newsletter. Each issue has surpassed my expectations, and they aren't just useless marketing fluff; they are substantive and interesting issues. I'm really enjoying each one. GREAT JOB HP! Thanks, bruce Edited: 10 Dec 2008, 12:49 a.m.

 Re: HP Solve calculator newsletterMessage #3 Posted by Karl Schneider on 10 Dec 2008, 3:00 a.m.,in response to message #1 by Matt Kernal Hi, Matt -- Long time no post! Thanks for the link; I'd forgotten about the HP Solve newsletters. They don't measure up to the old Hewlett-Packard Journal, but the time, effort, and budget funds expended are not even remotely comparable. This headline from the December 2008 issue was a bit startling: Technical corner: Sinus, Cosine and Tangent To find the Sin, Cos and Tan of a number, some heavy trigonometric algorithms are needed. Make it easy with your HP calculator and these step-by-step instructions. "Sinus"? Sure, "Sin" and "Cos" are sinusoidal, but... And why are "heavy trigonometric algorithms" and "step-by-step instructions" necessary? Wouldn't a single keystroke provide the desired answers? As it turns out, the three-page article describes the CORDIC algorithm. Maybe this time it'll make sense to me, as published references and Eric Smith's thoughtful summary of almost two years ago haven't quite done the trick... "Coronate rotation" and "Cartesian plan" slipped through proofreading in the article. ;-) A recap of HHC 2008 with group photo is in the same issue. -- KS Edited: 10 Dec 2008, 3:05 a.m.

And the photo showed mainly guys. One of the reasons why I wouldn't attend... ;-) Are there no female math teachers anymore?

 Re: HP Solve calculator newsletterMessage #5 Posted by Don Shepherd on 10 Dec 2008, 7:53 a.m.,in response to message #4 by George Bailey (Bedford Falls) There are plenty of female math teachers. None of them are HP calculator geeks, however.

Mainly? I see only ONE gal in the picture. At least from the other pictures we know what Cyrille and Gene look like. Anyone care to provide a legend to the group picture?

 Re: HP Solve calculator newsletterMessage #7 Posted by Matt Kernal on 10 Dec 2008, 1:29 p.m.,in response to message #6 by Martin Pinckney I believe George meant to write manly guys. ;-) Quote: Anyone care to provide a legend to the group picture? If someone gave the go-ahead (because most are in the FBI Witness Protection Program ;-), I think I could match-up about 90% of the names on Joe's list, with the HP Source photo.

 Re: HP Solve calculator newsletterMessage #11 Posted by Alain Mellan on 10 Dec 2008, 10:40 a.m.,in response to message #10 by Egan Ford Some translation problem maybe? ;-) sinus is french for sine Edited: 10 Dec 2008, 10:41 a.m.

I couldn't figure that out from the newsletter alone. So, yes my remark was very insightful ;-) Thank you for it, I found it very interesting and fun to read. Quote: Next time, why don't you, people of hpMuseum right an article in french for a change! Calm down, I wasn't trying to diminish the value of your article. In fact I was astonished to read that Americans don't ever use the words sinus or cosinus in their textbooks. My goal was to point out to them that it's a very common term in so many languages, including my own native tongue which is not English.

No harm done! :-) Thanks again for your article! Regards, George Bailey P.S. Why is it that the articles are never signed? I would love to know who did the hard work writing them.

 Re: HP Solve calculator newsletterMessage #22 Posted by cyrille de Brébisson on 10 Dec 2008, 10:57 p.m.,in response to message #3 by Karl Schneider hello Quote: "Sinus"? Sure, "Sin" and "Cos" are sinusoidal, but... And why are "heavy trigonometric algorithms" and "step-by-step instructions" necessary? Wouldn't a single keystroke provide the desired answers? Because the whole point of the articles is to try to explain what happen when you press that ONE key :-) Quote: As it turns out, the three-page article describes the CORDIC algorithm. Maybe this time it'll make sense to me, as published references and Eric Smith's thoughtful summary of almost two years ago haven't quite done the trick... "Coronate rotation" and "Cartesian plan" slipped through proofreading in the article. ;-) Actually, it's a little bit more than just a description of cordic, it also deals with how to implement it in a 10 based system. usualy cordic is implemented in a 2 base system, and things change quite a bit... and so do the optimisations... as for the smelling mistakes... well, sheet happen :-) cyrille

 Re: HP Solve calculator newsletterMessage #23 Posted by Karl Schneider on 12 Dec 2008, 3:20 a.m.,in response to message #22 by cyrille de Brébisson Hi, Cyrille -- OK, thank you again for your article, which I will take time to study. The "smelling mistakes" [sic] do demonstrate the value of review and proofreading, by a native-speaker peer or tech writer if possible... I noticed that you had an article regarding square root in an earlier edition of the newsletter. I assume that you might have consulted three similar articles from Hewlett-Packard Journal in the 1970's. For the benefit of Forum readers: one of these is available from HP's website, and all three of them are available on the MoHPC CD/DVD set: Algorithms and Accuracy in the HP-35 (June 1972): -- CD/DVD file 72JUN35.PDFhttp://www.hpl.hp.com/hpjournal/72jun/jun72a2.pdf Personal Calculator Algorithms I: Square Roots (May 1977) -- CD/DVD file 77MAYAL1.PDF Personal Calculator Algorithms II: Trigonometric Functions (June 1977) -- CD/DVD file 77JUNAL2.PDF Note: All other Journals available on-line are from the 1990's. Navigate back to the "hpjournal" directory to find them. -- KS Edited: 12 Dec 2008, 3:34 a.m.

 Re: HP Solve calculator newsletterMessage #25 Posted by Karl Schneider on 13 Dec 2008, 2:54 p.m.,in response to message #24 by Didier Lachieze Didier -- Thank you for setting the record straight, and pointing out that link under the same directory. This issue actually had been discussed previously in the Forum, but I forgot about the complete collection. (In fact, I had downloaded one of these Journals a year ago.) Unlike these Journal scans on the HP website, the scans of the same material in the MoHPC CD-ROM set or DVD-ROM v6.00 set are specifically of calculator articles, are not in color, and are not text-searchable. However, they are much easier to read on the screen. -- KS Edited: 13 Dec 2008, 2:56 p.m.
