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°
