微分

在数学中,微分是对函数的局部变化率的一种线性描述。微分可以近似地描述当函数自变量的取值作足够小的改变时,函数的值是怎样改变的。当某些函数\scriptstyle f的自变量\scriptstyle x有一个微小的改变\scriptstyle h时,函数的变化可以分解为两个部分。一个部分是线性部分:在一维情况下,它正比于自变量的变化量\scriptstyle h,可以表示成\scriptstyle h和一个与\scriptstyle h无关,只与函数\scriptstyle f\scriptstyle x有关的量的乘积;在更广泛的情况下,它是一个线性映射作用在\scriptstyle h上的值。另一部分是比\scriptstyle h更高阶的无穷小,也就是说除以\scriptstyle h后仍然会趋于零。当改变量\scriptstyle h很小时,第二部分可以忽略不计,函数的变化量约等于第一部分,也就是函数在\scriptstyle x处的微分,记作\displaystyle f'(x)h\displaystyle \textrm{d}f_x(h)。如果一个函数在某处具有以上的性质,就称此函数在该点可微。

Differential calculus 微分

The graph of a function, drawn in black, and a tangent line to that function, drawn in red. The slope of the tangent line equals the derivative of the function at the marked point.
The tangent line at (x,f(x))

In mathematics, differential calculus is a subfield of calculus concerned with the study of the rates at which quantities change. It is one of the two traditional divisions of calculus, the other being integral calculus.

The primary objects of study in differential calculus are the derivative of a function, related notions such as the differential, and their applications. The derivative of a function at a chosen input value describes the rate of change of the function near that input value. The process of finding a derivative is called differentiation. Geometrically, the derivative at a point is the slope of the tangent line to the graph of the function at that point, provided that the derivative exists and is defined at that point. For a real-valued function of a single real variable, the derivative of a function at a point generally determines the best linear approximation to the function at that point.
