WebJan 10, 2015 · I am using atan2(y, x) for finding the polar angle from the x-axis and a vector which contains the point (x,y) for converting Cartesian coordinates to polar coordinates. But, in my program which will be used for calculations to move a robot, atan2 is a very computationally expensive procedure. What are ways to approximate atan2's result with … Web1 day ago · math. atan (x) ¶ Return the arc tangent of x, in radians. The result is between -pi/2 and pi/2. math. atan2 (y, x) ¶ Return atan(y / x), in radians. The result is between -pi and pi. The vector in the plane from the origin to point (x, …
WebThe four-quadrant inverse tangent, atan2(Y,X), returns values in the closed interval [–π, π] based on the values of Y and X, as shown in the graphic. In contrast, atan(Y/X) returns results that are limited to the interval [–π/2, … WebMar 16, 2024 · Atan2( a, b ) equals Atan( b/a ), except that a can equal 0 (zero) with the Atan2 function.
