Re: LOG function or ln Message #8 Posted by CaribbeanHP12c on 8 Apr 2008, 10:17 p.m., in response to message #7 by Chuck
Chuck:
First off... thanks for the knowledgeable reply. I love that app you built, do you distribute the same thing as in .app for the iTouch... that would be great to have!
So, yes i use the same formula:
ln{(12000/200).04 +1}
n= ------------------------
ln (1+.04)
ln{3.4}
n= --------
ln(1.04)
n= 31.20227
I can arrive at the correct answer, but chuck as you have already illustrated and proved with your great app, i would like to KEY in the same values (as i did in your app) and get the exact answer, not 32 which the HP12c is giving me, with my Entered values that i wrote above in this post. When it comes to the exams and such i don't really want to be messing about with 2 different calculators and and solving annuity formulas by hand.
Plus, i am stuck on the HP12c, as a good friend and CFO of a company i started several years back swears buy it and would brag about it while he was depreciating the value of servers and then on to projecting stock prices. I have no choice but to learn. :)
Thanks again... long post, opps.
Caribbean, or better (Blake, but i live there)
