Six Trigonometric Functions

Question

If sin(θ)=-1, find all the angles which satisfy the given equation and condition.

Answer 1

sin(theta) = -1 at theta = 270 degrees

at that point cos(theta) = 0

tan(theta) = sin(theta)/cos(theta) is undefined because cos(theta) = 0

cot(theta) = cos(theta)/sin(theta) = 0

csc(theta) = 1/sin(theta) = -1

sec(theta) = 1/cos(theta) is undefined because cos(theta) = 0
