Plotting multiple equations on the 50g? Message #1 Posted by Ken Ratkevich on 27 Nov 2006, 6:38 a.m. Is there a simple answer to this question? The manual says it's possible but it doesn't describe how it's done. Ken

Re: Plotting multiple equations on the 50g? Message #2 Posted by Raymond Del Tondo on 27 Nov 2006, 8:48 a.m., in response to message #1 by Ken Ratkevich 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. Raymond

Re: Plotting multiple equations on the 50g? Message #3 Posted by Ken Ratkevich on 27 Nov 2006, 9:20 a.m., in response to message #2 by Raymond Del Tondo 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

Re: Plotting multiple equations on the 50g? Message #5 Posted by Chuck on 27 Nov 2006, 5:51 p.m., in response to message #4 by Brad Barton I think you can also set two equations equal to each other, stored in EQ: 'x^2=cos(x)'

I think, they removed the feature on later RPL models. Marcus

Re: Plotting multiple equations on the 50g? Message #7 Posted by Marcus von Cube, Germany on 7 Dec 2006, 4:05 a.m., in response to message #6 by Marcus von Cube, Germany 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. Marcus
