基本导数公式有：(1nx)’=1/x、 (sinx)'=cosx、 (cosx)’=-sinx。

求导公式

c'=o(c为常数)

(x~a)'=ax^(a-1), a为常数且a≠0

(a ^x)'=a^x1na

(e^x)'=e x

(1ogax)’=1/(x1na), a>0且a≠1

(1nx)’=1/x

(sinx)' =cosx

(cosx)’=-sinx

(tanx)'=(secx)^2

(secx)’=secxtanx

(cotx)'=-(cscx)^2

(cscx)'=-csxcotx

(arcsinx)'=1/√(1-x^2)

(arccosx)’=-1/√(1-x ^2)

(arctanx)’=1/(1+x^2)

(arccotx)'=-1/(1+x^2)

(shx)'=chx

(chx)'=shx

(uv)'=uv'tu'v

(u+v)'=u'+v'

(u/)'=(u'v-uv')/ ^2
