Let $latex T$ be the set of all times, and let $latex G(t)$ measure how good day $latex t$ is. Translate the logical statement $latex \exists t_1 < 0 \exists t_2 < 0 \forall t \in T ( (t \ne t_1 \land t \ne t_2) \Longrightarrow (G(t) < G(t_1) \land G(t) < G(t_2)),$ where time $latex 0$ is today.…

Horrible False Analogy – Mean Green Math

I had forgotten the precise assumptions on uniform convergence that guarantees that an infinite series can be differentiated term by term, so that one can safely conclude $latex \displaystyle \frac{d}{dx} \sum_{n=1}^\infty f_n(x) = \sum_{n=1}^\infty f_n'(x)$. This was part of my studies in real analysis as a student, so I remembered there was a theorem but…
