Hello,
I want to make a simple TI-89 titanium function that will simply take two resistor values as inputs and output the parallel combination of the two. I have no problem doing this as a program, but the problem is that it outputs the answer to the PrgmIO tab. The problem, however, is that I want to be able to use the function in expressions (like a cos() function for example). I assume that writing a function (as opposed to a program) would do this, but i'm not sure how to make it output to the home screen... when i try to use my function, it gives an error when trying to use the Disp function.
Anybody have any idea how to do this?
