Thus, write the equation in the form of dy / dx = g ( y / x ) by doing suitable algebra carefully. After setting y = vx , substituting, and doing a bit more algebra, you will end up looking at the separable equation . Separating variables and integrating leads you to . After doing that and completing the integration, you’ll obtain or an equivalent beast. You may then finish this by replacing v above with y / x . Additional algebra will lead to the same 1-parameter family of implicit solutions as the exact
