Web18 nov 2024 · arctan ( k tan ( x) ) ≈ kx. should be a very good approximation for small x. Here’s a plot of our function for varying values of k. Each is fairly flat in the middle, with slope equal to its value of k. As k increases, f ( x; k) becomes more and more like a step function, equal to -π/2 for negative x and π/2 for positive x, i.e. WebArctangens. De arctangens of boogtangens, aangeduid door atan, arctan of bgtan, en ook wel door [1] is een cyclometrische functie in de wiskunde die de inverse functie is van de tangens indien het domein van de tangens beperkt wordt tot het interval . Deze beperking is nodig vanwege het periodieke karakter van de tangens.

WebSeveral 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: [citation needed] when measuring in radians, an angle …
