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. … WebSep 17, 2024 · There are perfectly good reasons why you might be interested in allowing for any angle between -pi and pi. It's just that, if you don't make the -pi/2,pi/2 restriction then MATLAB won't recognize that atan2(sin(alpha),cos(alpha))=alpha. Under your assumption that alpha is between -pi and pi, it should recognize that, but for some reason it doesn't.

If you had to divide, use element-wise division (the ./ operator) instead of matrix division (the / operator.)
WebJan 18, 2008 · So, I just multiply the result of atan by 2.0 to get the same result as the HLSL atan2 function. No, HLSL atan2 (x,y) == GLSL atan (y,x) GLSL provides two atan-operators. One taking 1 parameter and one taking 2 parameters. The one with 2 parameters is the equivalent of atan2. N. WebDescription. atan () returns the angle whose trigonometric arctangent is y,x or y_over_x, depending on which overload is invoked. In the first overload, the signs of y and x are used to determine the quadrant that the angle lies in. The values returned by atan in this case are in the range -PI and PI. Results are undefined if x is zero.
In computing and mathematics, the function atan2 is the 2-argument arctangent.
