@tcarroll010 Could you help this is Pre-Calculus?

jdoe0001 · Answer

you kinda got a blank there

sorry$$-3\pi/4$$

anonymous · Answer

I'm using the Unit Circle but I'm not sure how to get the pint.

anonymous · Answer

Would the terminal side be 135 degrees?

jdoe0001 · Answer

well, negative values go COUNTERCLOCKWISE
so they don't go upward and to the left
negative angles are measured downwards and to the left
for example   $\cfrac{3\pi}{2} = -\cfrac{\pi}{2}$

jdoe0001 · Answer

wait, I said that backwards, they go CLOCKWISE

jdoe0001 · Answer

or the same way  a CLOCK hands move

So −3π/4 = pi/4

jdoe0001 · Answer

well, 4/4 of pi, is a "pi", so 3/4 of pi, will be less than that by 1/4
so

Ok I understand that "well, 4/4 of pi, is a "pi", so 3/4 of pi, will be less than that by 1/4" but what is the image showing? One piece of pi is 4/4 which you put but|dw:1372803480453:dw|
