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

theta = 4

    I assume that Ø = 4 radians

    2π radians = appr 6.28
    3π/2 = 4.7
    π rad = 3.14

    so 4 radians must be in quadrant III
    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!
