Hello dear TI programmers,

I want to program this formula in to a program so I can repeatedly use it with different variables.
However I haven't found a program on the web and i have zero TI 84+ programming experience.
I was hoping some one could program it or could tell me how to do it.

I hope I'm at the right adress!
If i posted this in the wrong sub, please tell me,

Cédric
Luckily, all of those are pretty easy to program in a program! First, do you know how to compute those on the homescreen? If you do, then you already know how to write a program to compute them. Let's take the last one as an example. On the homescreen, you might compute that equation like this (where ~ is the negation symbol typed using the [(-)] key):

Code:
```4->A                 4 5->B                 5 9->C                 9 (A-(B-A)^2/(C-2B+A))^~2         (whatever the answer is)```
If you want to make that a very simple program, you need to take that equation on the last line and add two things to it:
1) A Prompt statement that asks the user for the values for A, B, and C.
2) A Disp command, which displays the result of a computation as a number (or string, or list, or matrix...)
Here's how this program might end up looking:

Code:
```PROGRAM:GETF :Prompt A,B,C :Disp "f=" :Disp (A-(B-A)^2/(C-2B+A))^~2```

So far so good? Some of my colleagues might yell at me here, but if you have an interest in pursuing calculator programming a bit, I worked hard on a book that teaches TI-BASIC.

Not at all. The cost of this book is minimal compared to the cost of the calc. and will save hours of pain struggling to solve problems such the one posed above.
