Answer:

Yes

Step-by-step explanation:

1) Cos 300 = Cos (360 - 60) = Cos 60 {Cos 360 - theta = Cos theta}

= 1/2

Sin 300 = Sin (360 - 60) = -Sin 60 = $\frac{-\sqrt{3}}{2}$

3) 3π/4 = 3*180/4 = 135

Cos 135 = Cos (90 + 45) = -Cos 45 = $\frac{-\sqrt{2}}{2}$

Sin 135 = Sin (90 + 45) = Sin 45 = $\frac{\sqrt{2}}{2}$
