The inverse trigonometric functions are the inverse functions of trigonometric functions in mathematics. They are the inverses of the sine, cosine, tangent, cotangent, secant, and cosecant functions, respectively. They’re most commonly applied to calculate an angle from one of the angle’s trigonometric ratios.
The inverse of the tangent function is the arctan function. It returns the angle with a given tangent.
For example,
If the tan of 45° is 1:
Tan(45°) = 1
Then the arctan of 1 is 45°:
arctan(1) = tan-1(1) = 45°
