Have a question about using Wolfram|Alpha?Arctan (or) tanis the inverse function of the tangent function. The domain must be restricted because in order for a function to have an inverse, the function must be one-to-one, meaning that no horizontal line can intersect the graph of the function more than once Mathematically, we represent arctan or the inverse tangent function as tanx or arctan(x). Arctan definition. i.e., If y = tanx then tan y = x. Try it. = xtan−1(x) −∫ 2x+ x2 dx. Tangent only has an inverse function on a restricted domain, inverse. As there are a total of six trigonometric functions, similarly, there areinverse trigonometric functions, namely, sinx, cosx, tanx, cosecx, secx, and cotx.

It is usually denoted as arctan x and the formula is θ = arctan(Perpendicular / Base) 反正切函數.Arctan calculator. (This convention is used throughout this article.) This notation arises from the following geometric relationships: [ citation needed ] when measuring in radians, an angle of θ radians will correspond to an arc whose length is rθ, where r is the radius of the circle The integral of arctan is the integration of tan inverse x, which is also called the antiderivative of arctan, which is given by ∫tanx dx = x tanx½ ln |1+x| + C, where C is the constant of integration.
