不定积分 Antiderivative

（重定向自Primitive function）

在微积分中，一个函数 \begin{smallmatrix} f \end{smallmatrix} 的不定积分，也称为原函数或反导数，是一个导数等于 \begin{smallmatrix} f \end{smallmatrix} 的函数 \begin{smallmatrix} F \end{smallmatrix} ，即 \begin{smallmatrix} F' = f \end{smallmatrix} 。不定积分和定积分间的关系由微积分基本定理确定。

\begin{matrix} \int f(x)dx = F(x)+C\end{matrix}

其中 \begin{smallmatrix} F \end{smallmatrix} 是 \begin{smallmatrix} f \end{smallmatrix} 的不定积分。这样，许多函数的定积分的计算就可以简便地通过求不定积分来进行。

Antiderivative 不定积分

（重定向自Primitive function）
The slope field of F(x) = (x3/3)-(x2/2)-x+c, showing three of the infinitely many solutions that can be produced by varying the arbitrary constant C.

In calculus, an antiderivative, primitive function, primitive integral or indefinite integral of a function f is a differentiable function F whose derivative is equal to the original function f. This can be stated symbolically as F ′ = f. The process of solving for antiderivatives is called antidifferentiation (or indefinite integration) and its opposite operation is called differentiation, which is the process of finding a derivative.
