y=(2x^2+4x+1)^12,dy/dx=?

dy/dx,y=(1+x+x^2)e^x y=x^2x,求dy y=f[(x-1)/(x+1)],f'(x)=arctanx^2,求dy/dx,dy y=(2x^2+4x+1)^12,dy/dx=? Y=x√(1-x^2 )+arcsinx,dy=? dy/dx=(e^x+x)(1+y^2)通解 y=x^2+3x+1 求dy y=sin^2 {x/(x+1)} 求dy y=2^x-cosx/1-x 求dy (x^2)dy+（y^2)dx=dx-dy y=[sin(x^4)]^2,则dy/dx=?,dy^2/dx^2=?,dy/d(x^2)=? [(2-x)dy/dx+y]²+(x-ydx/dy)²=4 y = x^2 sin 4x,求dy,求dy 已知x=y^2-4y,求dy/dx dy/dx=x(1+y^2)/y通解 y=e^2x,dy= 微分方程 dy/dx=(-2x)/y y=sinx/x^2,求dy
