atan2 (y, x) returns the angle θ between the positive x -axis and the ray from the origin to the point (x, y), confined to (−π, π]. In computing and mathematics, the function atan2 is the 2- argument arctangent.

Use this arctan calculator to easily calculate the arctan of a given number. Online arctangent calculation tool to compute the arcus tangens function in degrees or radians. Supports input of decimal numbers (0.5, 6, -1, etc.) and fractions (1/3, 3/4, 1/6, -4/3 etc.).

That's right, the function \arctan returns an argument in range [-\pi/2,\pi/2] radians, and the sum of two of them will be in a range twice larger. We do have \tan (\arctan (2x) + \arctan (3x))=\frac {5x} {1-6x^2}, ...

Use this arctan calculator to quickly find the inverse tangent. Whether you're looking for a simple answer to the question "what is an arctan?" or are curious about the integral or derivative of arctan, you've come to the right place.
