## Online Tutoring Is The Easiest, Most Cost-Effective Way For Students To Get The Help They Need Whenever They Need It.

Inverse tangent is the inverse of the commonly used trigonometric function, tangent of an angle. Inverse tangent is also called as the Arctan of a given number. By finding inverse tangent of a value gives us back its respective angle. Inverse tangent calculator is the online quick tool which can easily calculate the inverse tangent of any number.

Example 1: Find the inverse tangent value of 1.

The notation for the inverse tangent of 1 tan-1(1)

In order to find the inverse tangent of ‘1’, we use the following method:

’1’ can be written as ‘tan(45°)’ since  tan(45°) = 1

Hence  tan-1(1) = tan-1(tan45°)

Now the answer by the ‘tangent’ formula is   45°

Hence the angle in degrees for the inverse tangent, tan-1(1) = 45°

Example 2: Find the inverse tangent value of 0.

The notation for the inverse tangent of 0   tan-1(0)

In order to find the inverse tangent of ‘0’, we use this method.

’0’ can be written as ‘tan(0°)’ since  tan(0°) = 0

Hence  tan-1(0) = tan-1(tan0°)

Now the answer by the ‘tangent’ formula is  0°

Hence the angle in degrees for the inverse tangent, tan-1(0) = 0°
