How do I use atan2?

How do I use atan2?

To convert the output of the ATAN2 function from radians to degrees the formula is:

1. =ATAN2(x,y)*180/PI() // Returns angle in degrees. Alternatively, the degrees formula can be used to convert the angle to degrees.
2. =DEGREES(ATAN2(x,y))// Returns angle in degrees. Difference Between ATAN and ATAN2.
3. = ATAN2(x,y) = ATAN(y/x)

What is atan2 vs Atan?

atan is the general form of inverse tangent that gets a value and returns the associated angle in radian. But atan2 gets two values of y and x and assumes a complex number as x + iy and returns its phase.

What is atan2 in math?

Description. The Math. atan2() method returns a numeric value between -π and π representing the angle theta of an (x, y) point. This is the counterclockwise angle, measured in radians, between the positive X axis, and the point (x, y) . Because atan2() is a static method of Math , you always use it as Math.

What is an Arctangent?

arctangent (atan or tan-1 on some calculators) is used to calculate the angles of a right triangle. It works opposite of the tangent function. While tangent will find the ratio of the two sides of a right triangle when given an angle, arctangent can find the angle given the ratio.

What is the math module in Python?

What is math module in Python? The math module is a standard module in Python and is always available. To use mathematical functions under this module, you have to import the module using import math . This module does not support complex datatypes.
