TI-89- How do I make programs?

  1. Sep 17, 2012 #1
    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 [Broken]

    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.

    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.
