Discover the power of our Atan2 Calculator, an indispensable online tool for determining the precise angle of a point (x, y) relative to the positive x-axis. Unlike standard arctan, atan2 correctly identifies the quadrant, providing accurate results in both radians and degrees. Essential for geometry, physics, and game development.
Formula:
The atan2(y, x) function is a variant of the arctangent function that calculates the angle (θ) in standard position between the positive x-axis and the ray from the origin to the point (x, y). It considers the signs of both y and x to correctly place the angle in the appropriate quadrant, yielding a result typically in the range of [-π, π] radians or [-180°, 180°] degrees.
