WebOct 17, 2012 · A simple answer that will work for principal angles (angles over the range θ = -π to +π) is as follows: θ' = -atan2 (2cos θ, 1.5sin θ) θ = atan2 (2cos θ', -1.5sin θ') where the first equation is your forward transformation, and the second equation is one of many inverse transformations. The reason for this is that what you're doing is ... WebATAN2 ( y, x) returns the arc tangent of the two numbers x and y. It is similar to calculating the arc tangent of y / x, except that the signs of both arguments are used to determine …

WebP = atan2(Y,X) returns the four-quadrant inverse tangent (tan-1) of Y and X, which must be real. The atan2 function follows the convention that atan2(x,x) returns 0 when x is mathematically zero (either 0 or -0). …
WebIn computing and mathematics, the function atan2 is the 2- argument arctangent. By definition, is the angle measure (in radians, with ) between the positive -axis and the ray from the origin to the point in the Cartesian plane. Equivalently, is the argument (also called phase or angle) of the complex number.
atan2 (−0, +0) = −0; atan2 (−0, −0) = − π. This definition is related to the concept of signed zero. In mathematical writings other than source code, such as in books and articles, the notations Arctan [15] and Tan−1 [16] have been utilized; these are capitalized variants of the regular arctan and tan −1. See more 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 The 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 and an arbitrary vector in the 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 constant, equal to arctan(y/x). Hence for x > 0 or y ≠ 0, Thus the See more The $${\displaystyle \mathrm {atan2} }$$ function was originally designed for the convention in pure mathematics that can be termed east-counterclockwise. In practical … See more The function atan2 computes the principal value of the argument function applied to the complex number x + i y. That is, atan2(y, x) = Pr arg(x + i y) = Arg(x + i y).
