Equations with the Dependent Variable Missing
For a second-order differential equation of the form y” = f(t, y'),
the substitution v = y', v' = y" leads to a first-order equation
of the form v' = f(t, v). If this equation can be solved for u,
then y can be obtained by integrating = v. Note that
one arbitrary constant is obtained in solving the first-order
equation for u, and a second is introduced in the integration
for y. Use this substitution to solve the given equation.
