Why do differential equations have a reputation for being so challenging
ODEs are literally all trivially easy
PDEs are either trivial or unsolvable so we don’t even try or we just pretend they’re separable
Also there’s like five PDEs you’ll ever use
>Laplace
trivial
>Heat
easy
>Schrodinger
somewhat challenging
>black scholes
never used
>navier stokes
fine this one is hard
