Am I crazy, or does 11pi/4 lie in quadrant 3? That's what the back of my book says. But when I count it out on the unit circle it lands in quadrant 2 where 3pi/4 is located.
 
Physics news on Phys.org
11pi/4=2pi+3pi/4. So it lies in the same quadrant as 3pi/4. You aren't crazy.
 
Actually, I think I really am. The original question was asking for t = -11pi/4, which would put me at quadrant 3.

Thanks
 
Well, at least you know how to do the problem. Now you just have to learn to read it correctly.
