WebOnline arctan(x) calculator. Inverse tangent calculator.Enter the tangent value, select degrees (°) or radians (rad) and press the = button. WebExplanation: For tan 120 degrees, the angle 120° lies between 90° and 180° (Second Quadrant ). Since tangent function is negative in the second quadrant, thus tan 120° value = -√3 or -1.7320508. . . Since the tangent function is a periodic function, we can represent tan 120° as, tan 120 degrees = tan (120° + n × 180°), n ∈ Z.
