Question

Find the reference angle, theta prime, when theta=5 radians. Write your answer in radians.

Answer 1

(2π-5) radians ≈ 1.2831853 radians

Explanation:

The reference angle is the magnitude of the acute angle made with the x-axis. The value of θ is greater than 3π/2, so the reference angle is ...

... θ' = abs(θ -2π) = 2π-5 . . . . radians
