Question

What is the value of arctan (- sq rt 3)

Answer 1

Answer:

120 , 300 degrees ( for angles between 0 and 360 degrees).

In radians this is 2π/3, 5π/3 radians.

Step-by-step explanation:

Arctan ( - sq rt 3)  is the angles ( in radians or degrees) for which the tangent is - sq rt 3.

Arctan  sq rt 3 = 60 degrees or π/3 radians.

As the tangent is negative in the 2nd and 4th quadrants arctan(-sq rt 3) = 120 ,  300 degrees.
