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 constant, equal to arctan(y/x). Hence for x > 0 or y ≠ 0, Thus the gradient of atan2 is given by Informally representing the function atan2 as the angle function θ(x, y) = atan2(y, x) (which is on… WebFeb 1, 2013 · Remarks. The atan function calculates the arctangent of x.atan2 calculates the arctangent of y/x (if x equals 0, atan2 returns π/2 if y is positive, -π/2 if y is negative, or 0 if y is 0.). atan has an implementation that uses Streaming SIMD Extensions 2 (SSE2). See _set_SSE2_enable for information and restrictions on using the SSE2 implementation.. …
