WebMar 24, 2015 · \$\begingroup\$ In Picture #2, there are two graphs shown. The axes are not clear to me, so I'm going to talk about them as if they are perfectly normal X and Y. X is positive to the right, Y is positive up. The top one has a … 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.

In computing and mathematics, the function atan2 is the 2-argument arctangent. By definition, $${\displaystyle \theta =\operatorname {atan2} (y,x)}$$ is the angle measure (in radians, with $${\displaystyle -\pi <\theta \leq \pi }$$) between the positive $${\displaystyle x}$$-axis and the ray from the origin to the point See more The ordinary single-argument arctangent function only returns angle measures in the interval $${\displaystyle {\left[-{\tfrac {1}{2}}\pi ,+{\tfrac {1}{2}}\pi \right]},}$$ and when invoking it to find the angle measure between the x-axis … See more As the function atan2 is a function of two variables, it has two partial derivatives. At points where these derivatives exist, atan2 is, except for a … See more The $${\displaystyle \mathrm {atan2} }$$ function was originally designed for the convention in pure mathematics that can be termed east-counterclockwise.
