solving x^2=const for x / root simplifications Hello, Apart from the rest of my course (using TI Voyage 200 ;) ), I'm using an HP 50g (2.09) for a few weeks now and I like it a lot. I noticed two things I could neither explain to me nor find anything about it in the group archives though; so I hope you could have some hints. Firstly, I tried to solve a si... 10 Dec 2007 00:37
PEQUM equation manager update Just a note for anyone that uses my equation managing program PEQUM. I've added the ability to assign units to your variables so you can solve easily with units. I needed this capability for a class I was taking, so I threw it in there during one class period. It isn't extremely intuitive to use and I'd intended ... 10 Dec 2007 00:37

In FIX mode the calculator rounds numbers, e.i. in FIX3 "0.00051" and "0.0009" are both displayed... 10 Dec 2007 00:37

Romberg implementation John Meyers, I've been playing around with integration techniques the past few days and came across something you wrote about the Romberg method a few months back. You wrote: vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv The Romberg method of numeric integration is a "sampling" method, which makes su... 10 Dec 2007 00:37
Programming Finally have time to really learn my calculators. I want to learn to program them since one of them is always with me and my computer is not. I want to program for the math problems in some of the math problem books. I don't know weather to use sys RPL, user RPL, or C on the computer and transfer over to calculat... 10 Dec 2007 00:37 |
