Atan y atan2
WebThe math.atan2() method returns the arc tangent of y/x, in radians. Where x and y are the coordinates of a point (x,y). The returned value is between PI and -PI. Syntax. … WebThe four-quadrant inverse tangent, atan2(Y,X), returns values in the closed interval [–π, π] based on the values of Y and X, as shown in the graphic. In contrast, atan(Y/X) returns results that are limited to the interval [–π/2, π/2], shown on the right side of the diagram.

For $ (x, y) \ne (0, 0)$ is $\operatorname {atan2} (y, x)$ the angle between the positive x-axis and the ray from the origin to the point $ (x, y)$ in the Euclidean plane, with $-\pi < \operatorname {atan2} (y, x) \le \pi$. The points $ (x, -y)$ and $ (x, y)$ are symmetric with respect to the x-axis. cooking a roast on a pellet grillIn computing and mathematics, the function atan2 is the 2-argument arctangent.
