Question

We will evaluate sin(315°) by finding the reference angle of 315°.
What the reference angle of 315°?We'll call this angle a.
This will give us that sin(315°) = - sin(a) since 315° is in the
O first quadrant
O second quadrant
O third quadrant
O fourth quadrant
Thus sin(315°)

We will evaluate sin (5) by finding the reference angle of 5-
6
