look at the unit circle on the last page of the attached cheat sheet

anonymous · Answer

find the point on the unit circle corresponding to the angle of 135 degrees

anonymous · Answer

what do you see for the coordinates?

anonymous · Answer

i have one its-sqrt2/2, sqrt2/2

anonymous · Answer

i realize you do not see $(-1,1)$ but instead you see $(-\frac{\sqrt{2}}{2},\frac{\sqrt{2}}{2})$

anonymous · Answer

so it (-1, 1)

anonymous · Answer

they are the same except one is negative and the other is positive
that means if you go further out, you will get to the point $(-1,1)$

anonymous · Answer

yes
you can also use the "reference" triangle |dw:1374072591257:dw|

anonymous · Answer

thanks

anonymous · Answer

if you put in in the right place on the coordinate axis, you will get an angle of 135 degrees |dw:1374072667091:dw|
