What is the arctan square root of 3?

When considered in radians, the arctan of the square root of 3 is equal to pi over 3, or 1.047. If the square root of 3 is considered in degrees, the arctan of the square root of 3 is equal to about 59.97.

If converted from radians to degrees, the arctan of the square root of three is equal to 60 degrees. The function arctan is also known as the inverse tangent and can be written as tan^(-1) or atan. Whereas regular trigonometric functions are used to determine the trigonometric ratio from an angle, the inverse functions are used to determine the size of an angle given the trigonometric ratio. The ratio is typically given in radians.
