y=Incos(arctanx)求dy谢谢了.

求下列函数的导数与微分 1.y=arctanx³,求dy. 谢谢~~ y=ln(arctanx),求y`及dy y=f[(x-1)/(x+1)],f'(x)=arctanx^2,求dy/dx,dy 求下列函数的导数与微分 1.y=arctanx³,求dy. 设y=sin^2•e^arctanx.求dy/dx 设f x 为可导函数,y=f^2(x+arctanx),求dy/dx 一道高数题.求导y=x的x次方+arctanx 求dy/dx y=arctanx,求y' 设y=[(x^2+1)/2]*(arctanx)^2-xarctanx+(1/2)ln(1+x^2),求y'以及dy 1.y=x arctanx - 1/2 ln(1+x^2) 求dy 2.y=tan(3x^2+1) 求y的导数即y' 3 2x+y=dy/dx求高手解答谢谢. 求y''+arctanx=0通解
