# Math Help - Which Quadrant?

1. ## Which Quadrant?

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.

2. $\frac{5\pi}{4} = \pi+\frac{\pi}{4} \Rightarrow$ 3rd

$\frac{7\pi}{4} = 2\pi-\frac{\pi}{4} \Rightarrow$ 4th
