nice explanation but I think you forgot to emit the minus at the end when you canceled it out when doing uv - u'v because the complex conj of -ihf is ihf* right?

What?
* Why cancelling dx with dx?
* Why omitting the - sign in the integration by-parts formula? if because complex conjugating i, then in what step you exactly took the complex conjugate of i and why??

Thanks.

Very poorly explained, you cant just cancel the dx’s with no explanation as to why or how that’s valid.
