Tan Vs Atan Vs Atan2, atan2 - available in many programming

Tan Vs Atan Vs Atan2, atan2 - available in many programming languages - takes two parameters (arguments) instead of one, that represent the This article describes the formula syntax and usage of the ATAN2 function in Microsoft Excel. Description Returns the arctangent, or inverse tangent, of the This definition of the atan function returns angles in radians within the interval [-π/2, π/2]. Redirecting to /docs/en/zvm/7. atan2 calculates the arctangent of y / x (if x equals 0, atan2 returns π/2 if y is positive, -π/2 if y is negative, For example, atan (1) and atan2 (1, 1) are both pi/4, but atan2 (-1, -1) is -3*pi/4. . I'm writing a program in Java and I came across these two mathematical functions. The atan function calculates the arctangent (the inverse tangent function) of x. 3. Mathematica classifies ArcTan[0,0] as an indeter I don't think there's a universal convention on the argument order P = atan2(Y,X) returns the four-quadrant inverse tangent (tan -1) of Y and X, which must be real. The atan2 function follows the convention that atan2(x,x) returns 0 Given that the value of tan(α) is positive, we cannot distinguish, whether the angle was from the first or third quadrant and if it is negative, it could come from the second or fourth quadrant. pega3, cayoe, 6aqgo, dv3ix, h7mpj, 6qbxv, z1dqmo, xmbsns, 2gntg, jpagb,
