Your second integral in part 3 is incorrect. You should normally be able to integrate a function, then derive it to get the same function back. What happens if you take the derivative of ln(\sqrt{x}) ? Don't forget the Chain Rule!

Oh okay, thing is, that's the way the instructor did it, while we were asked to derive expressions for the total differential for dz and dy, then substitute the latter into the former, sorry if I wasn't clear. Thanks though!

Thanks for the reply! What do f_y and f_z refer to?

Homework Statement If f(x,y,z) = 0, then you can think of z as a function of x and y, or z(x,y). y can also be thought of as a function of x and z, or y(z,x) Therefore: dz= \frac{\partial z}{\partial x}dx + \frac{\partial z}{\partial y} dy and dy= \frac{\partial y}{\partial x}dx +...
