WebMar 2, 2016 · The result is between -pi and pi. The vector in the plane from the origin to point (x, y) makes this angle with the positive X axis. The point of atan2 () is that the signs of both inputs are known to it, so it can compute the correct quadrant for the angle. For example, atan (1) and atan2 (1, 1) are both pi/4, but atan2 (-1, -1) is -3*pi/4. WebDec 1, 2024 · Remarks.

WebATan2 converts rectangular coordinates (x,y) to polar (r,θ), where r is the distance from the origin and θ is the angle from the x-axis. Conversion of rectangular to polar coordinates. The equation for determining ATan2 is: tanθ = y / x (where θ is the angle). The ATan2 operation represents all quadrants in a Cartesian matrix (based on sign).
