- (u+v)'=u'+v'
- (u-v)'=u'-v'
- (uv)'=u'v+uv'
- (u/v)'=(u'v-uv')/v^2
- y=c(常数),y'=0
- y=pow(x,a),y'=a·pow(x,a-1)
- y=pow(a,x),y'=pow(a,x)·ln(a)
- y=log(a,x),y'=1/(xlna);特别的ln(x)=1/x
- y=sin(x),y'=cos(x)
- y=cos(x),y'=-sin(x)
- y=tan(x),y'=1/(cos(x)^2)
若y=f(g(x)),y'=f'(g(x))·g'(x),前提是g在x处可导,f在g(x)处可导
