Partial Differentiation with 2 variables

Homework Statement



When I write 'd' I mean the partial differentiation symbol 'del' here...

Find dz/dx and dz/dy of:

z=f(xy)

I'm guessing this isn't a case of simply pretending the 'f( )' isn't there, how do I approach this problem?

when you say
dz/dx
you want to find the first partial derivative of z in terms of x.
meaning, that you treat y as a constant and x as a veritable

similarly goes with dz/dy
