求导数,
(10) y=ln√x+√lnx (12)y=sinnx (14)y=sin^nx (16)y=cos^3 x/2
(18) y=lntanx/2 (20) y=lnlnx (22)y=1/(cos^n x) (24)y=sec^2 x/a+csc^2 x/a

求导数,(10) y=ln√x+√lnx (12)y=sinnx (14)y=sin^nx (16)y=cos^3 x/2(18) y=lntanx/2 (20) y=lnlnx (22)y=1/(cos^n x) (24)y=sec^2 x/a+csc^2 x/a
y=(sinx)^n
y'=n(sinx)^(n-1)*cosx
