There are two functions for calculating the inverse tangent or arctan in Excel. These two functions are ATAN and ATAN2 (“atan” is short for arctangent), and they each have specific uses depending on the desired results that you’d like to obtain and the inputs available.
This article describes the formula syntax and usage of the ATAN function in Microsoft Excel. Description. Returns the arctangent, or inverse tangent, of a number. The arctangent is the angle whose tangent is number. The returned angle is given in radians in the range -pi/2 to pi/2. Syntax. ATAN(number) The ATAN function syntax has the following ...
17 cze 2024 · The ATAN function of Excel enables you to find arctan from the given tangent of an acute angle in a right-angle triangle. You can also use the same function to calculate inverse tan when you have the length values of the opposite and adjacent sides of the respective acute angle.
The Excel ATAN function returns the inverse tangent or arc-tangent of a number. In geometric terms, the function returns the angle of a right-triangle given the ratio of its opposite side over its adjacent side.
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 ...
The Excel ATAN2 function returns the arctangent from x- and y-coordinates. In geometric terms, the function returns the radian angle corresponding to the input point. Purpose. Get arctangent from x- and y-coordinates. Return value. The angle in radians of the point. Syntax. = ATAN2(x_num, y_num) x_num - The x coordinate of the input point.
17 lut 2021 · In this simple guide, we are going to run through how to use the Excel ATAN function to calculate the inverse tangent of a given number. We will cover: What is an inverse tangent?
