Finding the solution of this equation

  1. Jan 2, 2010 #1
    Is the following formula solvable?

    [tex]\frac{dw}{dv}_{atw0}+\frac{dv}{dw}_{atv0}=0[/tex]

    Thanks very much~

    i am trying to solve a ODE using the method of characteristics

    now i found this equation, but i can't solve it:

    dy/dx = ( 2*y^2 - x^6)/(x*y)


    the solution of x = x(0)*exp(y*s)
    s is the parametrization

    the equation that i am trying to solve:

    xy* (du/dx) + (2*y^2 -x^6)*(du/dy) = 0 x>0 y => 0


    can someone help me. i have to found the ground characteristics
