Hi,
when I type
Plot3D[{-0.005553135*sin[15.708 x]*sin[7.85398 y]}, {x, 0, 0.2}, {y, 0, 0.4}]
in Mathematica, it only plot's an empty cube. In WolframAlpha it works fine. Does anybody know what the problem is?
Thank you very much!
Mathematica built in functions are capitalized, so sin should be Sin.
Thanks, that solved the problem!!!!!
Paste the code in the posting using the Code Sample button.
This works:
Plot3D[-0.005553135 Sin[15.708 x] Sin[7.85398 y], {x, 0, 0.2}, {y, 0, 0.4}]
