Question

How do you find the reference angle for 13pi/6 ?

Answer 1

@larryboxaplenty Quadrant I?

Answer 2

@larryboxaplenty is it the measure of the angle itself? pi/6?

Answer 3

its 30 degrees (390-360=30), which is just pi/6 in radian

a quick way to find the reference angle for anything in radian is to divide 180 by the denominator

so 180/6=30, and there's your reference angle
