Webarctan2x等于2arctanx吗 对于arctan(tan2x)，它相当于将x替换为了2x，所以同理可得arctan(tan2x)=2x。 但是对于arctan(2tanx)，其涉及反三角函数的二倍角公式，已经超出了大学高等数学的计算范畴。 WebThere are several arctan formulas, arctan identities and properties that are helpful in solving simple as well as complicated sums on inverse trigonometry. A few of them are given below: arctan (-x) = -arctan (x), for all x ∈ R tan (arctan x) = x, for all real numbers x arctan (tan x) = x, for x ∈ (-π/2, π/2)

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 … See more In mathematics, the inverse trigonometric functions (occasionally also called arcus functions, antitrigonometric functions or cyclometric functions ) are the inverse functions of the trigonometric functions (with suitably … See more Principal values Since none of the six trigonometric functions are one-to-one, they must be restricted in order to have inverse functions. Therefore, the result ranges of the inverse functions are proper (i.e. strict) subsets of … See more Finding the angle of a right triangle Inverse trigonometric functions are useful when trying to determine the remaining two angles of a See more • Arcsine distribution • Inverse exsecant • Inverse versine See more Derivatives of inverse trigonometric functions Main article: Differentiation of trigonometric … See more Since the inverse trigonometric functions are analytic functions, they can be extended from the real line to the complex plane. This results in functions with multiple sheets and branch points. One possible way of defining the extension is: See more • Weisstein, Eric W. "Inverse Tangent". MathWorld.
