| Mar 17, 2023 at 15:47 | comment | added | Iosif Pinelis | Do you have a single example of $o$ and $v$ with non-constant $ov$ such that (1) holds? If $v$ is $C^1$, then, by integration by parts, (1) can hold only if $ov$ is constant (and then (2) cannot hold). Also, why denote a function by $o$? Also, it is better to write $\int_a^b\varphi' vo$ or $\int_a^b\varphi' (x)v(x)o(x)\,dx$ instead of $\int_a^b\varphi' vo\,dx$. | |
