The derivative of a function can be interpreted either as a function whose value at x is equal to the gradient of the tangent line to the graph of y=f at x, or, alternatively, as a function that describes the instantaneous rate of change of y with respect to x at the point x.

一个函数的导数可以理解为一个函数的值无论是在x是等于切线的梯度的y图二F在x，或者，或者，作为一个函数描述瞬时速度y的变化的关于x的点x在f关于x的也可以表示为导数
