In mathematics, the inverse trigonometric functions (occasionally also called antitrigonometric, [ 1 ]cyclometric, [ 2 ] or arcus functions [ 3 ]) are the inverse functions of the trigonometric functions, under suitably restricted domains.
Arctan is the inverse tangent function that has a domain of all real numbers and a range of [-π/2, π/2]. Learn how to use arctan to find tangent values, special angles, composition of trigonometric functions, and solve trigonometric equations.
Definicja Arktanu. Arcus tangens x jest definiowany jako odwrotna funkcja styczna x, gdy x jest rzeczywiste (x ∈ℝ ). Gdy styczna y jest równa x: tan y = x. Wtedy arcus tangens x jest równy odwrotnej funkcji stycznej x, która jest równa y: arctan x = tan -1 x = y.
Definicja arcus tangensa. Funkcja arcus tangens jest odwrotną funkcją y = tan (x). arctan ( y ) = tan -1 ( y ) = x + kπ. Dla każdego. k = {..., - 2, -1,0,1,2, ...} Na przykład, jeśli styczna 45 ° wynosi 1: tan (45 °) = 1. Wtedy arcus tangens 1 wynosi 45 °: arctan (1) = tan -1 (1) = 45 °.
