The function atan() takes x and returns y of arc tangents (in radians), such that yi = tan-1xi, where -/2 < yi /2.
The function atan2() takes two arguments and returns quadrant correct arc tangents z (in radians), such that zi = tan-1 ( xi / yi ). For each element i, the expression atan2(xi, yi) is mathematically equivalent to:
At least one of the arguments xi or yi must be nonzero.
