HP 48G -- entering more than one equation into the PLOT application Message #1 Posted by Randal B on 23 Jan 2013, 11:48 p.m. In the User's Guide it says you can plot multiple equations together by entering them into a list in brackets {}, but it does not give any more explanation or examples. I am able to plot one equation fine, but when I try to do the list it won't work. For example, to plot both y = x^2 and Y=3x I tried entering {x^2+5 3 *x} (with a space separating the two expressions), but when I use the brackets it gets spread out like {x ^ 2 3 x} and after it starts plotting I get an error that says "Too few arguments."

I think you're just missing the single-quotes around the equations. In other words, just enter {'x^2+5' '3*x'}. The calculator uses the single-quotes to know where the equation starts and ends.
