Problem 6: In class, we showed that at an arbitrary point P with spherical coordinates
(r, 0, 0), the unit vector ↑ could be written in terms of the Cartesian unit vectors as
↑ = sin cos x + sin 0 sin oy + cos 0 2.
Determine the equivalent expressions for ✪ and in terms of â, ŷ, and 2 (i.e., in Carte-
sian components using spherical coordinates), and verify that all three in fact have unit
magnitude.
