| Hi Tianyi, Honestly don't try to understand it, it seems to be a mistake. It took me a while to understand what was going on. I'm a mathematician in discrete mathematics, so I have limited knowledge of complex analysis. When I wrote that lesson, I... |
| Hi Roberto, This is Marc, the instructor of the course for Discrete Math. The study group just finished today, the course framework will be available in a few days. Happy learning! Marc |
| Hello Peter, Indeed, as Dave pointed out, you're basically abusing of the [properties of expectation][1]. Notice f(E(x)) is equal to E(f(x)) if f(x) is a linear function. For non-linear functions, f(E(x)) is not equal to E(f(x)). Norm is not a... |
