Inverse Tangent Calculator: Find Arctan (atan) of Any Value

Calculate Inverse Tangent (Arctan)

Use our Inverse Tangent Calculator to quickly determine the angle (in degrees or radians) whose tangent is a given number. Ideal for students, engineers, and mathematicians, this tool simplifies complex trigonometric calculations, making it easy to find arctan(x) with precision.

Formula:

The inverse tangent function, also known as arctangent (atan or arctan), helps find the angle when the tangent of that angle is known. The formula is:

θ = atan(x)

Where:

  • θ represents the angle (in degrees or radians).
  • x is the tangent value (the ratio of the opposite side to the adjacent side in a right-angled triangle).
