EVALUATING TRIG FUNCTIONS GIVEN A POINT ON THE TERMINAL SIDE WORKSHEET

Use the given point on the terminal side of angle θ to find the value of the trigonometric function indicated.

Problem 1 :

tan θ ; (8, 18)

Problem 2 :

sec θ ; (√5, -2)

Problem 3 :

cos θ ; (√19, 9)

Problem 4 :

sin θ ; (3, -4)

Problem 5 :

sin θ ; (-6, 4)

Problem 6 :

cos θ ; (2, -2)

Problem 7 :

cot θ ; (-7, √15)

Problem 8 :

cos θ ; (-5, -12)

Problem 9 :

sin θ ; (-√7, 3)

Problem 10 :

tan θ ; (-11, -2)

Answer Key

1) tan θ = 9/4

2) sec θ = 3/√5

3) cos θ = √19/10

4) sin θ = -4/5

5) sin θ = 2/√13

6) cos θ = 1/√2

7) cot θ = √15/-7

8) cos θ = -5/13

9) sin θ = 3/4

10) tan θ = 2/11
