anonymous · Answer

can you draw a picture of what this is asking?

anonymous · Answer

what quadrant is $\theta $ in?

No, im supposed to use the unit cirle and stuff... really it would help me to know if -3pi/4 is the same as a positive 3pi/4. Because 3pi/4 is 135, but im not sure if a -3pi/4 would be 225?

anonymous · Answer

yes, it's basically the same but a  negative angle is just rotating clockwise.  
so instead of rotating 3/4 pi counter-clockwise,  a negative angle would rotate 3/4pi clockwise....

so it would be 225?

anonymous · Answer

well 225 would be a coterminal angle and u can use that to answer this question...

anonymous · Answer

ie, 225 degrees is in the same quadrant as $\large -\frac {3\pi}{4} $
