In complex analysis, a branch of mathematics, the residue at infinity is a residue of a holomorphic function on an annulus having an infinite external radius. The infinity is a point added to the local space in order to render it compact (in this case it is a one-point compactification). This space denoted is isomorphic to the Riemann sphere. One can use the residue at infinity to calculate some integrals. (Wikipedia).
Definition of infinity In this video, I define the concept of infinity (as used in analysis), and explain what it means for sup(S) to be infinity. In particular, the least upper bound property becomes very elegant to write down. Check out my real numbers playlist: https://www.youtube.co

Indeterminate Forms In this video, I introduce the concept of indeterminate forms and explain why it is necessary to even have calculus. Then, I go over the main forms, all while emphasizing that in each of them, there is a tug-of-war situation going on. Enjoy! Check out my Calculus Play

Touching Infinity: It's Not Out of Reach
The conventional way to represent the Real Number system is to think of the numbers as corresponding to points along an infinite straight line. The problem is that in this representation there is no place for "infinity". Infinity is not a real number. This video shows an alternate visua
