Change Plot3D[xtimesy[x y], {x, -5, 5}, {y, -5, 5}] to Plot3D[xtimesy[x, y], {x, -5, 5}, {y, -5, 5}] Cheers, Vittorio -----Original Message----- From: jujubaby at gmail.com [mailto:jujubaby at gmail.com] To: mathgroup at smc.vnet.net Subject: [mg52734] [mg52698] Newbie Question -- Plot3d::plnc X-No-Archive: Yes When I enter the following two statements into Mathematica 5: xtimesy[x_, y_] := x*y; Plot3D[xtimesy[x y], {x, -5, 5}, {y, -5, 5}] I receive a huge cascade of errors, all of this form: Plot3D::plnc: xtimesy[x\y] is neither a machine-size real number at \ {x,y}={-5.,-5.} nor a list of a real number and a valid color directive. What am I doing wrong? Thanks! -Jake
