Atan vs arctan
WebThe arctangent of the angle formed by the x-axis and a vector to point (1,2) is 1.10714871779409, which is equivalent to 63.434948822922 degrees. // This example demonstrates Math.Atan() // Math.Atan2() // Math.Tan() // Functions 'atan', 'atan2', and 'tan' may be used instead. WebThere's an angle in QII, namely 135 degrees, whose tangent is -1, and there's an angle in QIV, namely 315 degrees (or -45 degrees, if you prefer) whose tangent is -1. In order for arctan to be a function, arctan(-1) must have just one value, and the same has to be true for arctan(x), no matter what real number x stands for.

WebAug 7, 2024 · Whereas the syntax for arctan is arctan ( y / x), the syntax for arctan2 is arctan 2 ( y, x). Knowing the signs of x and y separately can determine if the angle lies in any of the four quadrants. The range of arctan2 is - π ≤ arctan 2 ( y, x) ≤ π or in degrees, -180 ∘ ≤ arctan 2 ( y, x) ≤ 180 ∘. WebJan 11, 2024 · $\begingroup$ (+1) One other reason I dislike the $\tan^{-1}$ notation is because it suggests that the $\tan$ function has an inverse. This is not true: $\tan^{-1}(\tan(x)) \neq x$ in general. People often say '$\tan$ has an inverse on a restricted domain', but when you restrict the domain of a function, you are creating a new one.
