Is there a reason why you chose to parameterize the sphere as in the slide, other than to bring up this point about cosine appearing for different reasons?

Could we parameterize the sphere differently and avoid having multiple cosines to confuse?

This question might be off-topic, but could the reason why there's a theta in the sphere integral be further illustrated?
