Atan Calculator

Atan, also known as arctangent of 'a' is the inverse tangent function of 'a', where 'a' is the real number. (i.e.,) Tan b = a, Then tan inverse or atan of a = b. Use this online calculator to find the arctangent of x.

Formula:

t = tan-1(x) Where, t = Inverse Tangent x = Value

Example

Inverse Tangent

Let us consider the value of x as 23
Solution :
Atan(23) = tan-1(23)
The value of Atan(23) is 87.5104 degrees
The value of Atan(23) is 1.5273 radians

Note:
1 ° = 0.0174532925 radians
