Mathematica 3D plot is empty

Posted 10 years ago

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!

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}]

Mathematica built in functions are capitalized, so sin should be Sin.
