① C'=0(C為常數(shù)函數(shù))
② (x^n)'= nx^(n-1) (n∈Q*);熟記1/X的導(dǎo)數(shù)
③ (sinx)' = cosx
(cosx)' = - sinx
(e^x)' = e^x
(a^x)' = (a^x)lna (ln為自然對(duì)數(shù))
(Inx)' = 1/x(ln為自然對(duì)數(shù))
(logax)' =x^(-1) /lna(a>0且a不等于1)
(x^1/2)'=[2(x^1/2)]^(-1)
(1/x)'=-x^(-2)
導(dǎo)數(shù)的四則運(yùn)算法則(和、差、積、商):
①(u±v)'=u'±v'
②(uv)'=u'v+uv'
③(u/v)'=(u'v-uv')/ v^2
