But I do have one question: will Elake20's Excel file work?

Click to expand...

It will work with a few corrections. Here is a modified improved version that has a TEST function so you can check the value of a Y Output for any X input.

M=(Scal_MAX - Scal_MIN)/(Inp_MAX - INP_MIN)

and

b=Scal_MIN - ( M * Inp_MIN)

Ron, I just got a TI-36X Pro. It does not has the keys you talk about. Do you know why?

the "new and improved" PRO model doesn't have the same keys ... one of our members (ceilingwalker) sent me an email the other day with a workaround for the PRO model ... I've been too swamped to go over it - but I'll see how it goes in the next day or so ...

or maybe ceilingwalker will drop by and answer the question for you ...
