atanmm

atanmm, also known as the arctangent of the product of two numbers, is a mathematical function. It is closely related to the standard arctangent function, atan(x). The atanmm function takes two arguments, say x and y, and calculates the arctangent of their product, xy. Mathematically, it is expressed as atan(xy).

This function is not as commonly encountered as the standard arctangent but can appear in certain mathematical contexts. For instance, it might be used in signal processing or in the analysis of specific geometric transformations where the product of coordinates or variables plays a significant role. The output of atanmm, like atan(x), is typically an angle in radians, with the range of values being between -pi/2 and pi/2.

The utility of atanmm often lies in its ability to simplify expressions or to represent certain relationships more concisely than might be possible using only the standard arctangent. In numerical computation, implementations of atanmm would typically first compute the product xy and then apply the arctangent function to the result. This approach is straightforward and efficient.
