Arctangent

An Arctangent is an inverse function of a tangent function.

• Context:
  • It is denoted as [math]\displaystyle{ arctan(x) }[/math] and defined as [math]\displaystyle{ arctan=tan{-1}(x) }[/math] where [math]\displaystyle{ x }[/math] is a variable.

  • In mathematics, the inverse trigonometric functions (occasionally called cyclometric functions ) are the inverse functions of the trigonometric functions (with suitably restricted domains). Specifically, they are the inverses of the sine, cosine, tangent, cotangent, secant, and cosecant functions. They are used to obtain an angle from any of the angle's trigonometric ratios. Inverse trigonometric functions are widely used in engineering, navigation, physics, and geometry.
