Hey everyone. So, here's the problem I have:
z = x^2 + y^2
x = r*cos(theta)
y = r*sin(theta)
I need to calculate the partial derivative (dz/dx) while holding r
constant. [...]
Seems to me what you want is z_theta / x_theta, i.e., the ratio of two
partial derivatives with respect to theta, which of course assumes
constant r.
