Mathmaniac also has a series about group theory, inspired by 3B1Bs series about calculus and linear algebra. I love chemical formulae and this is one of my favourites. Determine whether the series \(\displaystyle{ \sum_{n=1}^{\infty}{ \frac{(n! We talked about our experiences of studying for a PhD and how our careers have developed as a result. Finally, here is this posts obligatory link to a quantum computing video. [emailprotected] If possible, evaluate \(\displaystyle{ \sum_{n=1}^{\infty}{ (e^{1/n} - e^{1/(n+2)}) } }\). \(\displaystyle{ \sum_{n=1}^{\infty}{ \frac{n^n}{(n! TheGermanFox has only uploaded three videos, but his musical proof of why e is irrational is actually really good and I cant get it out of my head. To bookmark this page and practice problems, log in to your account or set up a free account. If it is true, prove it. Determine whether the series \(\displaystyle{ \sum_{n=1}^{\infty}{ e^{-n}\sin(n) } }\) converges or diverges. Unless otherwise instructed, determine the convergence or divergence of these series. If \(\displaystyle{ \sum_{n=1}^{\infty}{ a_n } }\) diverges, then \(\displaystyle{ \sum_{n=1}^{\infty}{ 1/a_n } }\) must converge. This podcast, hosted by Grant Sanderson, has just started recently, but I can already recommend the conversations with Steven Strogatz and Sal Khan (of Khan Academy fame).
