what is terminal side

Question

Let , (−7,2)

 be a point on the terminal side of θ

.Find the exact values of cosθ

, secθ

, and cotθ

. 

Answer 1

Draw and label a diagram!

h = √53

cos θ = -7 / √53

sec θ = -√53 / 7

cot θ = -7 / 2

Answer 2

(-7, 2) is the point for "alpha".

Since this is a rt triangle "gamma"=90deg.

Your terminal side is (side c) or the hypotenuse.

Without any measurements; that's the best I can do.
