18.100B Real Analysis (Spring 2025, MIT OCW): Lecture 19

18.100B Real Analysis

18.100B Real Analysis (Spring 2025, MIT OCW). Instructor: Prof. Tobias Holck Colding. This course gives an introduction to analysis, and the goal is twofold:

1. To learn how to prove mathematical theorems in analysis and how to write proofs.

2. To prove theorems in calculus in a rigorous way.

The course will start with real numbers, limits, convergence, series and continuity. We will continue on with metric spaces, differentiation and Riemann integrals. After that, we will move on to differential equations. (from ocw.mit.edu)

Lecture 19 - Fundamental Theorem of Calculus

We will show the key link between differentiation and integrals: the fundamental theorem of calculus. In fact, we give two versions of this key theorem. We will also discuss improper integrals as well as integrals of unbounded functions.
