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

Convert F into cartesian coordinates from spherical

F = -4*theta*e_r + 1e_phi

r(t) = 2, theta(t) = 4t, phi(t) = pi / 2

2. Relevant equations

x = rsin(theta)cos(phi)

y = rsin(theta)sin(phi)

z = rcos(phi)

3. The attempt at a solution

Where I'm having problem is converting F into Cartesian coordinates.
