Which quadrant do the following angles lie in: 1. (5pie) / (4) 2. (7pie) / (4) I think it has something to do with whether the angle is between 0 and pie/2 or between pie/2 and pie, but I'm not sure how to classify them.

$\displaystyle \frac{5\pi}{4} = \pi+\frac{\pi}{4} \Rightarrow$ 3rd $\displaystyle \frac{7\pi}{4} = 2\pi-\frac{\pi}{4} \Rightarrow$ 4th
