1. The problem statement, all variables and given/known data Compute the surface integral: g = xyz on x^2+y^2+z^2 = 1 above z^2=x^2+y^2. 2. Relevant equations 3. The attempt at a solution I'm only doubtful about the parameterization. Under normal circumstances, since x^2+y^2+z^2 = 1 is a sphere, we can write: r = (SinCos[v])i + (SinSin[v])j + (Cos)k. However, how do you account for the "above z^2=x^2+y^2." Do I simply sum the square of the x and y components and write: r = (SinCos[v])i + (SinSin[v])j + (Sin^2)k. Is this correct?
