WebJan 31, 2014 · atan2(vector1.y - vector2.y, vector1.x - vector2.x) is the angle between the difference vector (connecting vector2 and vector1) and the x-axis, which is problably not what you meant. The (directed) angle from vector1 to vector2 can be computed as. angle = atan2(vector2.y, vector2.x) - atan2(vector1.y, vector1.x); 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 … See more • hypot 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) = … See more Sums of $${\displaystyle \operatorname {atan2} }$$ may be collapsed into a single operation according to the following identity See more The realization of the function differs from one computer language to another: • In Microsoft Excel, OpenOffice.org Calc, LibreOffice Calc, Google Spreadsheets, iWork Numbers, … See more create schedule for employeesWebMar 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. create scheduler job
