导数表
① C'=0(C为常数函数) ② (x^n)'= nx^(n-1) (n∈R);熟记1/X的导数 ③ (sinx)' = cosx (cosx)' = - sinx (tanx)'=1/(cosx)^2=(secx)^2=1+(tanx)^2 (cotx)'=-1/(sinx)^2=-(cscx)^2=-1-(cotx)^2 (secx)'=tanx·secx (cscx)'=-cotx·cscx (arcsinx)'=1/(1-x^2)^1/2 (arccosx)'=-1/(1-x^2)^1/2 (arctanx)'=1/(1+x^2) (arccotx)'=-1/(1+x^2) (arcsecx)'=1/(|x|(x^2-1)^1/2) (arccscx)'=-1/(|x|(x^2-1)^1/2) ④(sinhx)'=coshx (coshx)'=sinhx (tanhx)'=1/(coshx)^2=(sechx)^2 (coth)'=-1/(sinhx)^2=-(cschx)^2 (sechx)'=-tanhx·sechx (cschx)'=-cothx·cschx (arsinhx)'=1/(x^2+1)^1/2 (arcoshx)'=1/(x^2-1)^1/2 (artanhx)'=1/(x^2-1) (|x|<1) (arcothx)'=1/(x^2-1) (|x|>1) (arsechx)'=1/(x(1-x^2)^1/2) (arcschx)'=1/(x(1+x^2)^1/2) ⑤ (e^x)' = e^x (a^x)' = (a^x)lna (ln为自然对数) (Inx)' = 1/x(ln为自然对数) (logax)' =x^(-1) /lna(a>0且a不等于1) (x^1/2)'=[2(x^1/2)]^(-1)
(1/x)'=-x^(-2)
