I'm new to the software, and am having trouble with a simple command:
Plot3D[Sin[xy], {x, 0, 3}, {y, 0, 3}];
This is giving me: Plot3D::plnc: Sin[xy] is neither a machine-size
real number at {x, y}={0., \
0.} nor a list of a real number and a valid color directive
I must be missing something obvious, what could I be doing wrong here?
I don't think you need to load any packages to do this, do you?
