Find the value of:
tan^-1 (-sqrt. 3)
Thank you, Tami
Answer by scott8148(6628) (Show Source): You can put this solution on YOUR website!
the angle whose tangent is -sqrt(3) is part of a 30�-60�-90� triangle in the 2nd quadrant (tangent is negative)

the reference angle in the 2nd quadrant is 60�, so the angle is 120� or 2pi/3 radians
