y=（sin）^2*x,dy=

y=（sin）^2*x,dy= sin(x^2+y^2)=x,求dy x=sin(y/x)+e^2 求dy/dx y=sin^2 {x/(x+1)} 求dy y=sin(x^2),求dy/d(x^3) y=e^sin(x^2+根号x),求dy y=sin(x^3),求dy/d(x^2) y=x*sin(lnx) 求dy sin(xy)=x+y,求dy 设sin（x^2+y）=x,求隐函数y的微积分dy y=sin(x^2),dy/dx=? y = sin²（x²）求 dy / dx y=sin(x^2+1) 求dy请指示 y = x^2 sin 4x,求dy,求dy y=[sin(x^4)]^2,则dy/dx=?,dy^2/dx^2=?,dy/d(x^2)=? 设y=arcsin(sin²1/x）,求dy.设y=arcsin(sin^2 1/x）,求dy. 若y=sin^2（2-3x）,求dy. 设sin（xy）-x^2y=0,求dy／dx,求导什么的都要疯了!
