The ATAN2 function in Excel is a mathematical function that calculates the arctangent of the specified x- and y-coordinates. This function takes two arguments, the x-coordinate and the y-coordinate, and returns the angle in radians between -π and π. This function is commonly used in trigonometry and can be utilized for a variety of applications, such as finding the direction of a vector or determining angles in geometric shapes. By inputting the x- and y-coordinates into the ATAN2 function, users can quickly and accurately calculate the arctangent without having to perform complicated mathematical equations. This feature makes it a useful tool for professionals and students alike in various fields, including engineering, physics, and mathematics.
This article describes the formula syntax and usage of the ATAN2 function in Microsoft Excel.
Description
Returns the arctangent, or inverse tangent, of the specified x- and y-coordinates. The arctangent is the angle from the x-axis to a line containing the origin (0, 0) and a point with coordinates (x_num, y_num). The angle is given in radians between -pi and pi, excluding -pi.
Syntax
ATAN2(x_num, y_num)
The ATAN2 function syntax has the following arguments:
X_num Required. The x-coordinate of the point.
Y_num Required. The y-coordinate of the point.
Remarks
A positive result represents a counterclockwise angle from the x-axis; a negative result represents a clockwise angle.
ATAN2(a,b) equals ATAN(b/a), except that a can equal 0 in ATAN2.
If both x_num and y_num are 0, ATAN2 returns the #DIV/0! error value.
To express the arctangent in degrees, multiply the result by 180/PI( ) or use the DEGREES function.
