Hello,
I was working on Harold T. Davis
Introduction to Nonlinear Differential and Integral Equations
I saw this following equations
1-So equation 4 came as a result of chain rule applies on equation. 3 ?
2- how did equation 5 come about? And specially the "2" in second term.
3-What kind of calculus I should study, so I know this sort of stuff and I can save some time.
Thank you.
