求导数 c'=___ (x^n)'=____ (sin x)'=____ (cos x)'=____ (ln x)'=____ (loga x)'=____ (e^x)'=____
(a^x)'=____
答
c'=0
(x^n)'=n*（x^(n-1)
(sin x)'=cosx
(cos x)'=-sinx
(ln x)'=1/x
(loga x)'=1/(xlna)
(e^x)'=e^x
答
c'=0
(x^n)'= nx^(n-1)
(sin x)'=cosx
(cos x)'=-sinx
(ln x)'=1/x
(loga x)'=1/(xloga x)
(e^x)'=e^x
(a^x)'=a^xlna
