Question

几种常见函数的求导法

Answer 1

a^x'=a^x*ln(a) x^n'=n*x^(n-1) sinx'=cosx tanx'=(1/cosx)^2=(secx)^2=1+(tanx)^2 cotx'=-(1/sinx)^2=-(cscx)^2=-1-cot(x)^2 secx'=sec(x)*tan(x) cscx'=-csc(x)*cot(x) loga(x)=1/x/ln(a) asinx'=1/sqrt(1-x^2) acosx'=-1/sqrt(1-x^2) atanx'=1/(1+x^2) acotx'=-1/(1+x^2) asinh(x)’=1/sqrt(1+x^2)
