Okay, so I have a function that I want to differentiate (find the derivative of), but it's not a function type that they taught us how to differentiate in math, so I'm not sure about how I would do that.

Here's the function:
x(u, v)= a * cos (u) * sin (v)

The thing is, it has multiple inputs. Do I just do dxduv instead of dxdu or dxdv (though people usually call them dx/du or dx/dv instead; I just don't like drawing that line between the dx and du, etc., so I write it that way)? How would I find the derivative of that function?


Thanks in advance.

If the wiki steps aren't enough, just plug it into wolframalpha and click show steps.
