question is (-2, 3pi)
they want to find r>0 , -2pi< or equal to theta < 0
Isn't it just (-2 , pi)
because you subtract 2pi from 3pi don't you? But the book says the answer is (2, -2pi) What in the world?
The 2 in the actual correct answer is because of how polar coordinates are plotted it changed to a positive as a result. But the -2pi part instead of being pi, is not clear?
