Ti-89 Calculator Question
    #10782010 -

I'm working on statics over the summer, and want to know how to put in a function that returns three or four answers. Is this possible? I have no system link cable, so i can only do it on the calculator itself.

Working with vectors, i want to input all three i,j,k co-ords and have it return the manitude, and the three direction cosines: cos-1(i,j,k/magnitude).

Input should look like this: fctname(x,y,z). I have one fct that does a single direction cosine, but i still have to put in the magnitude. ie dircos(x,y) where x = i, j or k and y=magnitude.

Gotta love automating math.  I used to do that in middle school and finish my tests in like 10 mins.  I'm pretty sure the teachers at that time were like "whaaat? :wtf:"
