comment banach space bigger than $L^p$
the triangle inequality is deduced from the triangle inequality on norm of $L^p$ and the fact that $\sup(A+B)\leq \sup(A)+\sup(B)$

comment banach space bigger than $L^p$
don't mind about "bigger". I just think how to deduce that $(E,||.||_E)$ is banach space from the fact that $L^p$ are banach spaces. Obviously, by the norm defini like above, E is normed vector space. Is it banach?

How to know $\phi_n \to \phi$ in $L^p$ space?. We only have $\phi\in L^1$.

comment calculate double integral on quadrangle domain by changing of variables
I know you divide domain to small domains. But I want to calculate double integral which not need to divide. How can you do it?, or we have no any way to do it.
