Dear Frank, Since you are using Plot you can combine multiple plots on a single Plot command. The GraphicsArray displays an array of different plots. So, Plot[{Sin[x], x-x^3/6},{x,0,Pi}] will do it for you. since the curves are close for 0<x<Pi/4 you probably need to plot it with different colors or other PlotStyle definitions Plot[{Sin[x], x - x^3/6}, {x, 0, Pi}, PlotStyle -> {{}, Hue[0]}]. This will plot the curve of the polynomial with red color yehuda Frank Murphy wrote: >siafra at vaxsa.csied.unisa.it wrote: >: I'm a student in physics at the University of Salerno, Italy and I'm >using >: Mathematica 3.0 under Win95.
