Did I solve this diff eq substition problem properly?

  1. Feb 17, 2013 #1


    [itex]dv[/itex] = [itex]\frac{dy}{y}[/itex]-[itex]\frac{dx}{x}[/itex]


    [itex]ln(v+1)=ln x + C[/itex]

    v+1 = Cx
    ln(xy) +1 = Cx

    Would that basically be the complete answer?

    It might be interesting to solve this last equation for y=... and verify the answer with the initial equation.
