well, obviously only defined between -1<=z<=1

when x=0 , z= 1 ( ie in the zy plane it is a horizontal line )

I'm pretty sure it would be the same thing as f(x)=cosx but just in 3D cartesian coordinates. It would be graphed on the xz-plane.

Looking for something else?

you mean the xy plane right?

No..i'm pretty sure it's supposed by be in the xz-plane because it's a function of x and y. Kind of like f(x)=2x....the output is in the y direction. I think the output of f(x,y) is in the z-direction. Therefore, it would be the xz-plane

It will exist on all 3 planes.

It would look like an undulating wave which would have a cross section for every y value that looked like a cosine function in x and z. But that would extend along the y axis infinitely.

Yes...that's correct
