matlab求（d³y）/dx³+3（dy/dx）+2y=6的通解
并求满足y"（0）=1,y´（0）=2,y（0）=3的特解.

dsolve('D3y+3Dy+2y=6','x')
ans =
1/6*x^3+1/2*C1*x^2+C2*x+C3
>> dsolve('D3y+3Dy+2y=6','D2y(0)=1,Dy(0)=2,y(0)=3','x')
ans =
1/6*x^3+1/2*x^2+2*x+3

matlab求（d³y）/dx³+3（dy/dx）+2y=6的通解微分方程（y+1）²dy／dx+x³=0的通解为求微分方程的通解：x^2(d^2y/dx^2)=(dy/dx)^2+2x(dy/dx) 微分方程d^2y/dx^2-2dy/dx-3y=0的通解 (d^3y/dx^3)-2(d^2y/dx^2)-dy/dx+2y=0的通解怎么求? 求微分方程通解 d^2y／dx^2-e^y* dy／dx=0 求方程（x+y）dx+(3x+3y-4)dy=0的通解. 求微分方程dy/dx=（4x+3Y）/(x+y)的通解求微积分方程（y/x）*dx+(y^3+lnx)dy=0的通解求微分方程dy/dx=（y/x）^2+y/x的通解求dy/dx=(x+y)^2的通解求dy/dx=2x+y的通解.
