(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Find (∂a/∂x) if

x = r*sin(a)*cos(θ),

y = r*sin(a)*sin(θ),

z =r*cos(a).

The equations originally have phi in place of a, but I switched it to a for ease of typing.

2. Relevant equations

Chain rule?

3. The attempt at a solution

I'm not exactly sure where to start. I tried using the chain rule and differentiating with respect to x but then I just end up with too many unknown and nothing really simplifies. How exactly does one go about solving this problem? Thanks ahead of time for any help.
