I'm trying to graph
Plot3D[sin[x] cos[y], {x, -Pi/4, Pi/4}, {y, -Pi/4, Pi/4}]
for my Calculus homework, does anyone know why the graph I get is blank? I've tried experimenting with ranges but it hasn't changed at all? Thanks.
Thank you so much Bill that was the issue! I stared at it for a long time convince that I had the correct form. Thanks a ton!
Try capitalizing Sin and Cos and see if that helps.
Mathematica is fanatic about correct capitalization.
