An antiderivative is a function whose derivative is another given function. Learn about the definition, properties, techniques and examples of antiderivatives in calculus and physics.

Learn what antiderivatives are and how to find them using the reverse of differentiation. See how antiderivatives are used in rectilinear motion and other problems involving derivatives.

不定積分（英語： Indefinite Integration ），也可稱反導函數（ Antiderivative ）或原函数。 在 微积分 中， 函数 f {\displaystyle f} 的 不定积分 是一个 可微 函數 F {\displaystyle F} ，其 导数 等于原來的函數 f {\displaystyle f} ，即 F ′ = f {\displaystyle F'=f} 。

Learn how to find antiderivatives of functions and use the notation ∫ f (x) d x for the indefinite integral of f. See examples of antiderivatives of polynomials, trigonometric, and exponential functions.

本文介绍了不定积分和定积分的定义、运算法则、常用公式和例题，以及不定积分的线性运算法则和定积分的极限定义。不定积分是函数的原函数，定积分是函数在区间上的面积。

数学. 一、反导数的定义若函数 F 对任意 x\in I 有 F'\left ( x \right)=f\left ( x \right) ，则称 F 为区间 I 上 f 的反导数.二、反导数定理★ 若 F 为区间 I 上 f 的反导数，则其最一般的形式为 F\left ( x \right)+….

Learn what an antiderivative is and how to find it. An antiderivative is the opposite operation of differentiation and is also called an indefinite integral. See the illustrated definition and examples of antiderivatives.

Learn how to find antiderivatives of functions and their applications in rectilinear motion and other problems. Antiderivatives are functions with a derivative equal to a given function, and they have a general form with an arbitrary constant.

Learn how to find antiderivatives of functions using the integral sign and the indefinite integral. See examples of antiderivatives of sin x, cos x, and other functions.
