## Highlights of Calculus

Highlights of Calculus (Res.18-005, MIT OCW). Instructor: Professor Gilbert Strang. Highlights of Calculus is a series of short videos that introduces the basics of calculus - how it works and why it is important. The intended audience is high school students, college students, or anyone who might need help understanding the subject. The series is divided into three sections: 1) Introduction - Why Professor Gilbert Strang created these videos, 2) Highlights of Calculus - Five videos reviewing the key topics and ideas of calculus, Applications to real-life situations and problems, and 3) Derivatives - Twelve videos focused on differential calculus, More applications to real-life situations and problems.

 Lecture 04 - The Exponential Function

Professor Strang explains how the "magic number e" connects to ordinary things like the interest on a bank account. The graph of y = ex has the special property that its slope equals its height (it goes up "exponentially fast"!). This is the great function of calculus.
