Homework Statement
Taking the derivative of f(p)/p with respect to x,y,z separately. p = √(x^2+y^2+z^2) while f(p) is a scalar function that we don't know about
Homework Equations
f(p)/p
The Attempt at a Solution
I just wanted to know if the following is a legitimate way of doing it:
for partial derivative with respect to x: (f'(p)*pxp-f(p)*px)/p2
Similarly for derivative with respect to y: (f'(p)*pyp-f(p)*py)/p2
or is putting f'(p)*px invalid (i was thinking take the derivative of outside multiply by derivative of inside, but I'm not sure if the chain rule can be applied the way I did)
