Question

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

theta = 4

Answer 1

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 <b>quadrant III</b>
and <b>the reference angle is 4 - π = .8584</b>

check: since in III the tangent is positive,

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

Answer 2

thankyou!
