忍不住了,开导!🥵🥵🥵



(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)​
