How do I create a TI-89 program to calculate vector magnitudes?

[Peppino]

I would like to make a program for which you give two vectors, A and B, and it returns (A^2 + B^2)^0.5. How can I do this?

Go here

http://education.ti.com/guidebooks/graphing/89ti/TI89TitaniumGuidebook_Part2_EN.pdf

and scroll down the left hand column table of contents until you get to Programming. Then open up that section of the manual with a click. Step through the introduction page by page and it will show you how to enter and later run a program or function of your own.

thanks.

If you just want a simple program...

:Prompt a,b
:Disp (a^2-b^2)^.5

Now, that is the most basic version, and not very good looking, but it will get the job done.
