xy"-y’=x2的通解为______.
举一反三
- xy’=yln(y/x)的通解为
- 分解因式()x()3()y()-()2()x()2()y()2()+()xy()3()正确的是A.()xy()(()x()+()y())()2()B.()xy()(()x()2()﹣()2()xy()+()y()2())()C.()xy()(()x()2()+2()xy()﹣()y()2())()D.()xy()(()x()﹣()y())()2
- \(y=x\)方程\( y - y' = 1 + xy' \)的通解。
- 3. 方程$x y' + xy = y $的通解为 A: \[y=\mathit{c}\,{{e}^{-x}}\] B: \[y=\mathit{c}x\,{{e}^{-x}}\] C: \[y=\mathit{c}x\,{{e}^{-x^2}}\] D: \[y=\mathit{c}x^2\,{{e}^{-x}}\]
- 已知,y1=x,y2=x2,y3=ex为方程y"+p(x)y"+q(x)y=f(x)的三个特解,则该方程的通解为( ) A: y=C1x+C2x2+ex B: y=C1x2+C2ex+x C: y=C1(x—x2)+C2(x—ex)+x D: y=C1(x—x2)+C2(x2—ex)
