Question

高数十八个求导公式

Answer 1

1.(c)`=0 (c为常数）2.(x^a)`=ax^(a-1) (a∈R) 3.(a^x)`=a^(x)lna (a≠1且a＞0)
4.(e^x)`=e^x 5.(㏒a（x）)`=1/(xlna) (a≠1且a＞0) 6.(lnx)`=1/x
7.(sinx)`=cosx 8.(cosx)`= -sinx 9.(tanx)`=1/cos^2x=sec^2x
10.(cotx)`= -1/sin^2x= -csc^2x 11.(secx)`=sectanx 12.(cscx)`= -csccotx
13.(arcsinx)`=1/(（1-x^2）^1/2) 14.（arccosx）`= -1/(（1-x^2）^1/2)
15.(arctanx)`=1/(1+x^2) 16.(arccotx)`= -1/(1+x^2)
