If you were to disassemble the program file and search through it for the key, I'm sure you could crack it. It would just be kind of difficult and would take a while.
You can go to Barnes and Noble and buy a copy of the cliff notes for calculus, and I think you'd get more bang for your buck. Instead of having the computer do the work for you, and explain it to you, you can do the work yourself following the directions in the book. I know for me, I learn better that way. While I agree that the ideological reasoning is sound, calc software should be freeware and only that, there's no law preventing him from charging people for his work.
If you really wan't to protest it, you could write your own software to compete with his and not charge anything for it, instead of doing something illegal like stealing his work. Copyright laws still apply regardless of whether or not you agree with the ideals behind the copyrighted work.
AaroneusTheGreat, I perfectly agree with your opinion even if -trust me- it's not so easy to crack these programs. Someone should create another program capable of doing the same things. In fact I couldn't find any other program for ti89 on the internet capable of solving any integral and differential equation, step by step.
That's why I'm so interested in these 2 applications. Moreover I already lost, due to a crash, cme 9. That's why I'm trying to help all those people who, like me, got in trouble, and those who even can't afford such exagerate payments these softwares should be free, they shouldn't cost more than the calculator itself. So, if you can help me in anyway getting the passwords or creating alternative programs I'd be very glad.
Waiting for your replies. If you try to open the programs with MS Word, you'll see some text lines in the end which are related to the activation process. If someone can understand in which way these lines are related to the password and the ID, please let me know. Using a program like word wouldn't work very well, I was thinking more along the lines of a 68k assembly language disassembler.
That way it will preserve any hex or ascii codes that might be contained therein. Functions are included for TI-nspire and 68k-models.

There are also a variety of options that I added to provide the most convenience for you. Also, the user has more manually-controled options and less programed limitations.
The Newton-Raphson Iterative Method v1. Newton's Method Instructions: Run the program by typing nm in the home screen. Follow directions on screen - it's that simple. The reason I wrote this program was because most of the others ask for a range of accuracy. In this program, there is no range. The root will be at zero for as many decimal places as the calculator can compute. The only possible let-down I can think of is that I left out the given number of itterations function.
The itterations are, however, numbered if you only need a small number. It comes with all the possible options I could think of. Really nice! Newton's Method This is a simple program for newon s method. It s sometimes on the AP calc ab test. Anyways, you input the equation and a guess on the home screen and it displays 18 iterations on the I O screen. The n-dimensional version of the fmin on TI User guide is included in the.
