Solving DDE of a composition

58 Views Asked by At

If I have an ODE of the form: $$ f'(g(t))=h(t), $$ where $g$ is not necessarily invertible.
Is there a general solution for this type of ODE, if so when can I solve for f(t)?

This is not a well-posed question. Consider the simple case where $g(t) = t^2$ and $h(t) = t$. Set $t=1$, then the equation says $f'(1) = 1$. Now set $t = -1$, then the equation says $f'(1) = -1$. Clearly that does not make sense.
