Find the Reference Angle (6pi)/5
Problem
Solution
Identify the quadrant of the given angle
θ=(6*π)/5 Compare the angle to the standard quadrantal angles in radians.
Determine that since
π<(6*π)/5<(3*π)/2 the angle lies in Quadrant III.Apply the formula for the reference angle
θ′ in Quadrant III, which isθ′=θ−π Subtract
π from the given angle:(6*π)/5−π Simplify the expression by finding a common denominator:
(6*π)/5−(5*π)/5=π/5
