Re: 1st to 2nd order ODE IVP

Suppose I have a 1st-order ODE whose derivative can be expressed
without a 1st-order term. Is it ever beneficial to do this and apply
the discretization methods for the latter problem class, as opposed to
directly integrating the 1st-order problem?


Thanks,

Y' =F(x,Y) =>

Y'' = F_x(x,Y) + F_Y(x,Y)F(x,Y)

you mean this ?
this will be much harder to integrate than the first, I guess
