x=acos^2θ,y=sin^2θ,求dy/dx

x=sin(y/x)+e^2 求dy/dx y=sin[sin(x^2)] 则dy/dx=? 求∫dy/(2sin(y/2))=-∫sin(x/2)dx y=sin(x^2),dy/dx=? xy-sin(πy^2)=0 求dy/dx y=sin(x+y) 求dy/dx y=[sin(x^4)]^2,则dy/dx=?,dy^2/dx^2=?,dy/d(x^2)=? x=θ(1-sinθ) y=θcosθ 求dy/dx 设函数y=sin(2x²+1),求dy/dx,d²y/dx² 设sin（xy）-x^2y=0,求dy／dx,求导什么的都要疯了! 求微分方程dy∕dx=-sin^2(x+y)的通解 数学题求dy/dx设 f'(x)=sin√x 定义（x>0）,又y=f[e^(2x)]求dy/dx
