There is a basic derivative formula of 18.
The following is the basic derivative formula of 18 (y: original function; Y': derivative function):

1, y=c, y=0(c is a constant)

2, y=xxμ, y'=μxμ minus 1(μ is a constant and μ is not equal to 0).

3。 y=aAx,y'=aAxIna .y=eAx,y'=eAx .

4. y=logax, y' =1(A Xin) (a>0 and a =1); y=Inx,y'= 1/x .

5、y=sinx,y’= cosx .

6, y=cosx, y'= negative sinx.

7、y=tanx,y'=(secx)2= 1/(cosx)2 .

8.y=cotx, y'= negative (cscx)2= negative 1/(sinx)2.

9.y=arcsinx, y' =1√ (1minus x2).

10, y=arccosx, y'= negative1√ (1minus x2).

1 1、y=arctanx,y'= 1/( 1+x2).

12, y=arccotx, y'= negative 1/( 1+2).

13、y=shx,y'=chx .

14、y=chx,y'=shx .

15、y=thx,y'= 1/(chx)2 .

16、y=arshx,y'= 1/V( 1+x 12).

17, y=c(c is a constant) y'=0.

18, y=xny'=nxx(n minus 1).
