 Please Help!!!!!!!!Message #1 Posted by f15e on 4 Aug 2004, 3:45 p.m. In the following code at this link: I have tried to run the program but I don't seem to getting anything from it and I have made sure 3-4 times that the code had been entered correctly, which it was. I know I have to enter the coefficients before I run the program (XEQ S) but where do I enter them at? I tried XEQ I and XEQ J, but nothing. Can someone please walk me through this program; not the code, just using the program? I would greatly appreciate someone giving me an exact run through with a 3X3 example. Thanks!!!

For example, for the A coefficient, you STOre A. The answers will be on your stack, and you will have to rotate your stack to see them all (The R up arrow button, and R down arrow). See if that makes some sense. Also, if you are trying to learn the 33s, you might try reading some of the Learning Modules available at http://www.hp.com/calculators/scientific/33s/ These go through everything step by step (in RPN and Algebraic) and will help you better understand the calculator. -Ben Salinas 12345

 Re: Please Help!!!!!!!!Message #3 Posted by f15e on 5 Aug 2004, 1:54 p.m.,in response to message #1 by f15e Thanks Ben!! The program in the hp 33s manual has it to where you press the XEQ A key and then you are prompted for each coefficient, but this program is different. I now am able to use this program. I was trying to find the keys that would prompt me, but now I know I must enter the number then STO the number to the letter. Still more learning about this calc. to go. Thanks again.
