ATAN2

Definition: ATAN2 is a function that returns the arctangent of the quotient of two numbers.

Syntax: =ATAN2(x_num, y_num)

Situation: This formula is suitable when you need to find the angle between the x-axis and a point with given coordinates.

Example: If you have a point with coordinates (3,4), the angle between the x-axis and the point can be found using the formula =ATAN2(4,3), which returns a value of 0.93 radians.
