Maths Programs

Hey Charlie!
This is not a "regular" article that I'm writing -interesting fact, it is the 666th-, and it only concerns the Secondes but you can be interested anyway.
I just wanted to share some Maths Ti82 Programs I made (sorry Violette and others CASIO users).
The first thing you must do is to upload the Ti app.
So the first program is the Pythagorean theorem:
There are 3 of them:
This one is to calculate the hypothenuse. Click here to upload it.
Exemple: AB²=AC²+BC²
                  A      B       C
When you use it, it will show a "?"
You must put the length of B. You press enter and an other "?" appears, you put the length of C and enter. It will show the length of A.
This one is to calculate a length from the hypothenous and the other length. Click here to upload it.
Exemple: AB²=AC²+BC²
                  A      B       C
It's basically the same thing apart of putting the length of B first. You will put the length of A first, and the the length of B.
You must know that for these 2 programs it will show the square of the result in case it is not a whole number.
The third one is to know if a triangle is a right-angle triangle. Click here to upload it.
Exemple: AB²=AC²+BC²
                  A      B       C
You put A first, then the others length. It will show "Yes" or "No"
It is now over with Pythagoras.
The following one is to calculate the coordinates of the middle of A and B.
Exemple: A(3;2) B(2;4)
You put the coordinates in the right order (3 2 2 4 in this case) and it's done.
The last one is the theorem that we studied in class (calculating a length from the coodinates of 2 points). Click here to upload it.
It's -again- basically the same thing as the former program.
Exemple: A(3;2) B(2;4)
You put the coordinates in the right order (3 2 2 4 in this case) and it works, it's magic!
This is it for today, if there is a prolem with the programs, say it below, and if you want an other post, like it -I'm joking-!

P.S. I made a QR code of the blog, if you want it, it's here.
