what is the use of atan function Atan is used if we only know or are interested in y x not y and x individually So if p y x then to get we d use atan p You cannot use atan2 to determine the quadrant you
Several notations for the inverse trigonometric functions exist The most common convention is to name inverse trigonometric functions using an arc prefix arcsin x arccos x arctan x etc This convention is used throughout this article This notation arises from the following geometric relationships when measuring in radians an angle of radians will correspond to an arc wh The sine function sin takes angle and gives the ratio opposite hypotenuse The inverse sine function sin 1 takes the ratio opposite hypotenuse and gives angle And cosine and tangent follow a similar idea Example lengths are only to one

The math atan method returns the arc tangent of a number x as a numeric value between PI 2 and PI 2 radians Arc tangent is also defined as an inverse tangent function of x where x is the The inverse tangent is defined as tan 1 z i 2 log i z i z This definition of the atan function returns angles in radians within the interval 2 2 To find the four quadrant
Given a non right angle x of a right triangle tan x is the ratio frac o a where o is the length of the leg of the triangle opposite x and a is the length of the leg The four quadrant inverse tangent atan2 Y X returns values in the closed interval based on the values of Y and X as shown in the graphic In contrast atan Y X returns results that

ATAN x returns the arc tangent of x The arc tangent function is the inverse function of the tangent function and calculates the angle for a given tangent x The result is an angle expressed in radians To convert from radians to ATAN2 y x returns the arc tangent of the two numbers x and y It is similar to calculating the arc tangent of y x except that the signs of both arguments are used to determine the quadrant of the result The result is an angle expressed
The inverse tan is the inverse of the tan function and it is one of the inverse trigonometric functions It is also known as the arctan function which is pronounced as arc tan It is Atan is tan inverse that is gives you the angle given the tan When you call atan tan a 2 pi the answer will be a This will be inadequate for your application atan2 will take 2 arguments
