heres a problem from my textbook. How did they figure out those bounds for theta? On an exam i wont be able to use a calculator that graphs polar coords, and i should know how to do this anyways. Thanks

I understand how the bounds for r are set by converting http://www.mathhelpforum.com/math-he...01dddb08b5.png to polar coords but im not sure howe the bounds for theta (the -pi/2 to pi/2) are figured out.
