I need to know if there is a way on the TI89 to input a fxn through a program and have that fxn go into the y editor.
ex: if i were to enter 1 + x; 1 + x would go into y1.
I know this can be done on the TI83Plus, and am trying to find a way to do this with the TI89.
on the TI83, I can dobut trying to do this on the TI89 gives me an error:Code:Input "",Y1
I need to write this program for both calculators.Code:Input "", y1 or Input"", y2
Unless, there is a way to do it on both calculators to enter a fxn such as:
__ = x + y
and be able to plug in x and y^2.
This is for Euler's method.
I don't want to program it as a flash app, as I would need a TI83 counterpart, and a similar program to both would be nice.
edit: All I really need to know is how to enter something and place it in y1
