WebDec 22, 2012 · I gave a function for atan2() at the end of my post - myAtan2. This function takes 2 arguments (y,x) same as the "real" atan2(). To use myAtan2() you give 4 numbers: double myAtan2(double y, double x, int n, double& r_err ) y and x are the values used in the regular atan2(). n = # of terms to sum the power series. I used n = 50 in my examples. WebATAN2 function Description. Arc tangent of two numbers, or four-quadrant inverse tangent. ATAN2(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 the quadrant of the result. The result is an angle expressed in radians. star creature scooby doo https://bdmi-ce.com
