Suppose that a microphone has an optimal pickup area defined by 8+8sin(theta). This microphone is placed near a large, deep, rectangular theatrical stage so that the stage is nearest (4 units distant) at theta=pi/2. How much area is available to the troupe to perform on stage, in the microphone's optimal pickup area? (he spent an entire class period trying to solve this one)
If the stage is infinitely narrow, there will be no space for the actors to be heard. (Actually, if they attempt to get on the stage, they will be slice in two by it.)
However, assume a wide enough stage, we could get:
A genuinely "messy" problem, and I'm quite sure I've got it wrong. (I think I forgot to multiply by 64, then subtract the 16tan(φ) in front of the stage.)
