Explanation:
simplifys to
which has a reference angle of
. We can take the coordinates of
and make the x value negative to find the correct coordiantes. Then, using those coordinates, plug the into the trigonomic equations.
For example, sin in opposite/hypotenuse. So sin = 1/2 divided by 1. Then you can find the rest of the equations that way.
cos= adjacent/hypotenuse
tan= sin/cos
csc= hypotenuse/opposite
sec= hypotenuse/adjacent
cot= cos/sin
