- Basically, the difference between atan () and atan2 () is that atan2 () has a bigger range of return values. It can achieve this bigger range because it has more information to go on, from its two arguments, rather than the single argument of atan (). Depending on the application, you may want one or other of these functions
- Arctan Excel Functions: Use ATAN and ATAN2 to Calculate Inverse Tangent. 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

Normally when you calculate the inverse tangent, you are doing so for a question related to a triangle in which the two sides, x and y are lengths (positive numbers), and the resulting angle is between 0 and 90\(^{\circ}\) (\(\pi\)/2) * Atan2() is needed as atan() doesn't tell you the angle from the horizontal you need as it doesn't cope with quadrants*. This means that using atan for vectors (-2,2) and (2,-2) will give the same value. You would then to switch on the sign of yours arguments and add pi to the result. In addition, you have the divide by zero special case to consider that Jesse mentioned. Also atan2() works. atan2 is the 4 quadrants version of atan as the documentation states. It should therefore give different results for atan2(X,Y) and atan2(-X,-Y). It can also handle the case where X=0. Nagi Elabbasi Veryst Engineering . Nitzan Livneh.

The four-quadrant inverse tangent, atan2 (Y,X), returns values in the closed interval [-pi,pi] based on the values of Y and X, as shown in the graphic. In contrast, atan (Y/X) returns results that are limited to the interval [-pi/2,pi/2], shown on the right side of the diagram The arc tangent function with two arguments is called as the atan2. It can be represented as atan2 (y,x). It was initially used by the computer programming languages and now it has been used in various science and engineering fields. The results of the atan2 function will range between -π to +π Im Gegensatz zu atan() kann sie dabei die Vorzeichen beider Parameter beachten und so den Quadranten des Ergebnisses bestimmen.

Your atan3 defeats this feature. Well, I do not have a very exiting answer for you, I guess, but here. Atan2 () vs Atan (x/y) Using atan2 (x, y) is functionally equivalent to using atan (x/y). However, one difference is that, if you specify a y value of zero, atan2 () won't return an error, whereas atan () will. Here's an example using atan2 ()

The atan2() function returns the arc tangent of y/x, in the range [-pi, +pi] radians. If both y and x are 0.0, the result is undefined. If in POSIX mode, errno is set to EDOM. If the value of y or x is NaN, NaN is returned. If the result underflows, 0.0 is returned * atan returns 45\(^{\circ}\), because -1/-1 = 1, which is the same as 1/1 (red circle) * atan2 returns 135\(^{\circ}\), which is the correct answer accounting for the signs of x and y Additional overloads are provided in this header for other combinations of arithmetic types (Type1 and Type2): These overloads effectively cast its arguments to double before calculations, except if at least one of the arguments is of type long double (in which case both are casted to long double instead). This function is also overloaded in <valarray> (see valarray atan2) atan2 is a freaking useful function: given some y and x 1, it computes their four-quadrant arctangent 2, which is basically that coordinate's angle in polar form. These two beautiful Wikipedia diagrams explain why it's so much better than the naÃ¯ve atan(y/x): It also shows the reasons why I suffered a stroke of unsanity and whipped up my.

- In mathematics, the inverse trigonometric functions (occasionally also called arcus functions, antitrigonometric functions or cyclometric functions) are the inverse functions of the trigonometric functions (with suitably restricted domains).Specifically, they are the inverses of the sine, cosine, tangent, cotangent, secant, and cosecant functions, and are used to obtain an angle from any of.

- atan2 calculates the arctangent of y/x. atan2 is well defined for every point other than the origin, even if x equals 0 and y does not equal 0. For vectors, the returned vector contains the arctangent of each element of the input vector. Reference Implementation. atan2 for a float2 scalar could be implemented as an approximation like this
