Determine the values of the six trigonometric functions for the angle illustrated. When necessary, rationalize the denominator.

ANSWERS OPTIONS

sin θ = -(√2)/2, cos θ = (√2)/2, tan θ = 1, cot θ = 1, sec θ = √2, csc θ = -√2

sin θ = (√2)/2, cos θ = -(√2)/2, tan θ = -1, cot θ = -1, sec θ = -√2, csc θ = √2

sin θ = -2/3, cos θ = 2/3, tan θ = 1, cot θ = 1, sec θ = 3/2, csc θ = -3/2

sin θ = 2/3, cos θ = -2/3, tan θ = -1, cot θ = -1, sec θ = -3/2, csc θ = 3/2
