For the following point, let ? be the angle in standard position whose terminal side contains the point. Compute cos(?) and sin(?). P(-12, 35)

Question

Answer and steps.

Answer 1

Using Pythagoras the hypotenuse is 37.

 

sin θ = 35/37

sin θ ≈ 0.9459458459

 

cos θ = -12/37

cos θ ≈ = 0.324324324
