導數加減乘除公式?u(x),v(x)可導：(u±v)′=u′±v′，今天小編就來聊一聊關于導數加減乘除公式?接下來我們就一起去研究一下吧!
u(x),v(x)可導：
(u±v)′=u′±v′
(uv)′=u′v+uv′
(u/v)=(u′v-uv′)/v2 (v≠0)
常見導數公式：
(c)`=0 (c為常數）
(x^a)`=ax^(a-1) (a∈R)
(a^x)`=a^(x)lna (a≠1且a＞0)
(e^x)`=e^x
(㏒a（x）)`=1/(xlna) (a≠1且a＞0)
(lnx)`=1/x
(sinx)`=cosx
(cosx)`= -sinx
(tanx)`=1/cos^2x=sec^2x
(cotx)`= -1/sin^2x= -csc^2x
(secx)`=sectanx
(cscx)`= -csccotx
(arcsinx)`=1/(（1-x^2）^1/2)
(arccosx)`= -1/(（1-x^2）^1/2)
(arctanx)`=1/(1+x^2) 1
(arccotx)`= -1/(1+x^2)
