Activity 9.8.10 .
(a)
(i)
\((\rho, \theta, \phi)= (3, \frac{\pi}{3}, \frac{\pi}{2})\)
(ii)
\((\rho, \theta, \phi)= (4, \frac{4\pi}{3}, \frac{3\pi}{4})\)
(iii)
\((\rho, \theta, \phi)= (\sqrt{7}, 20^\circ, \pi)\)
(b)
Draw each of the points from
part a and show how the spherical coordinates of each point is being measured. You should use your plots to make sense of the rectangular coordinate measurements that were your answer to
part a .
