3个运算法则如下:

[u(x)±v(x)]=u(x)±v(x)[u(x) \pm v(x)]' = u'(x) \pm v'(x)

[u(x)v(x)]=u(x)v(x)+u(x)v(x)[u(x) \cdot v(x)]' = u'(x)v(x) + u(x)v'(x)

[u(x)v(x)]=u(x)v(x)u(x)v(x)v2(x) [\frac{u(x)}{v(x)}]' = \frac{u'(x)v(x) - u(x)v'(x)}{v^2(x)}

//上式的特殊形式:
[1v(x)]=1v2(x)v(x) [\frac{1}{v(x)}]' = -\frac{1}{v^2(x)}v'(x)
