Is there a simple answer to this question? The manual says it's possible but it doesn't describe how it's done.

Put the expressions you want to plot into a list,

and store the list in EQ.

I can't believe this isn't described in the manual.

Thanks. The answer is pretty obvious once you know what it is. As far as I can tell, this is not DIRECTLY addressed in the manual. But, since the manual (.pdf file) is 887 pages long, it is very likely that I just missed it.

Thanks again,

Ken

You can also plot each equation individually. Just don't press the erase button between plots.

I think you can also set two equations equal to each other, stored in EQ: 'x^2=cos(x)'

That's true for the 28S (probably also for the 28C). I think, they removed the feature on later RPL models.

I must stand corrected, the trick still works on the 48S and 48G and even on the 49g+/50g+. You have to store something like 'SIN(X)=COS(X)' in EQ and can than plot both curves simultaneously.
