Question

For an angle θ measured from the positive x-axis, the values of sin(θ) and cos(θ) are always which of the following?

greater than −1 and less than 1

greater than +1

less than or equal to −1 or greater than or equal to 1

less than −1

greater than or equal to −1 and less than or equal to 1

Answer 1

Answer #1

Sin(θ) and cos(θ) are greater than or equal to -1

And less than or equal to 1. Ans

maximum value of sin(θ) = 1

Minimum value of sin(θ) = -1

Maximum value of cos(θ) =1

Minimum value of cos(θ) =-1
