What is meant by "each region" in graphing trigonometric functions problems?

Question

I'm doing some homework for a pre-calculus class and we're doing a unit on graphing trigonometric functions. The homework has a blank where I'm meant to fill in "each region" I don't know what this means.

My teacher has not brought it up before, at least not using the phrase "each region". It could be referring to something I've already encountered, but I've had not luck trying to figure it out so far. Please help!!

Answer 1

Hi

I'm just guessing but "each region" could mean 1st 2nd 3rd and 4th quadrants. A 1st quadrant angle would be any angle between 0 and π/2 radians (0-90 deg). Second would be between π/2 and π and so on.

Hope this helps
