Input "f(x,y)",f ;Now f is the function in terms of x and y Input "x",x ;input an X value Input "y",y ;Input a Y value Disp f ;This will evaluate f

I hope that helps!

This is for a TI-89, someone in another forum showed me how to do it on an 84, but their method doesn't work for 89

I would like to prompt, input, request (or whatever) a function, store it as y1(x) (doesn't have to be y1(x) could be a(x) or anything else) and use the function later in a program. Here is an example although it clearly does not work.

Input "f(x)",f
f→ f(x,y)
Input "x",a
Input "y",b
Disp f(a,b)
Pause

The program will use two variables at most so no need to start using matrices. Any suggestions appreciated, I am fairly new to TI Basic so you might have to walk me though!
