The Sine function and the Cosine function

How do I bring in a surface into grasshopper that has the expressed function of sine(x) x cosine (y); so it is a double sided surface expressed by the multiplication of sine (x) x cosine (y)? Thanks

Thanks but how do you generate the same surface vertically?

Vertically in XZ plane? YZ plane ? With a rotation ? With a specified starting point ? Etc ...

Using Z instead of Y in the definition should answer your question though.

I didnt save it, just modify the definition you showed there, with 0 to 2*pi instead of 0 to 2, right click the X in the first Pt component and choose Graft, right click the P in SrfGrid and choose Flatten.

Ah well, and here is the "vertical" solution.
