y'^2-2yy'=y^2(e^x-1)求解,3Q
y'^2-2yy'=y^2(e^x-1)求解,3Q
y'^2-2yy'=y^2(e^x-1)求解,3Q
(y'/y)^2-2y'/y=e^x-1
(y'/y)^2-2y'/y+1=e^x
(y'/y-1)^2=e^x
y'/y-1=±e^(x/2)
(lny)'=1±e^(x/2)
lny=x±2e^(x/2)+C
y=e^(x±2e^(x/2)+C)
解常微分方程y'^2-2yy'=y^2(e^x-1)
y'^2-2yy'=y^2(e^x-1)求解,3Q
常微分方程的几个问题y'(2y-y')=y^2(sinx)^2y'^2-2yy'=y^2(e^x-1)求以上方程的通解
求微分方程yy'-e^(y^2-2x)=0倒是可以吧yy'看成整体,1/2[y^2]'-e^(y^2-2x)=0令y^2=u得u''/u'=2u'-4,
已知2x=3y,求xy/xx+yy-yy/xx-yy的值
yy''-(y')^2=y^2y'
yy''-(y')^2=y^2y'
求解微分方程:(1) 2yy‘‘=(y‘)^2+y^2 (2) yy‘‘+(y‘)^2+2x=0
3YY-2Y+6=83/2YY-Y+1=?YY=Y的平方
微分方程求解.yy''-(y')^2=1
求解:X+YY'=X(X^2+Y^2)
yy''-(y')^2=y^2lny
[2x-(x+y)(x-y)](yy-xx)
隐函数,y=e的x+y次幂怎么求导y=e^x+y x^3+y^3+cos(x+y)=0ln根号下x^2+y^2 -arctany/x=2xcosy=sin(x+y)cos(x^2y)=x这五道题怎么求导,都是高数中的隐函数求导。y'=y/1-yy'=3x^2-sin(x+y)/sin(x+y)-3y^2y'=y+x/x-yy'=cosy-cos(x+y)/cos
xx+2x+yy+6y+10=0求xx+yy的值
求微分方程yy'+(y')^2=2x的通解,
xx+12*12=yy(y-x=2)
xy+yy=10,x/2+y/3=6
