1. Determine the quadrant in which the terminal side of the angle is found and find the corresponding reference angle.

theta = 4

• math -

I assume that Ø = 4 radians

3π/2 = 4.7

and the reference angle is 4 - π = .8584

check: since in III the tangent is positive,

tan 4 = 1.1578
tan .8584 = 1.155 , close enough

thankyou!
