Understanding the Inverse Tangent Function

The inverse tangent function (arctan or tan-1) is the inverse of the tangent function. It returns the angle whose tangent is a specified number.

The mathematical formula is:

θ = arctan(x)

Where θ is the angle and x is the tangent value.

Applications

The inverse tangent function is widely used in:

  • Calculating angles in right triangles
  • Physics for determining angles of repose
  • Engineering for signal processing and control systems
  • Computer graphics for calculating rotations
