The Essence of Calculus, Chapter 1
Episode overview
Fecha de emisión
Abr 28, 2017
I want you to feel that you could have invented calculus for yourself, and in this first video of the series, we see how unraveling the nuances of a simple geometry question can lead to integrals, derivatives, and the fundamental theorem of calculus.
2017x5
The paradox of the derivative | Essence of calculus, chapter 2
Episode overview
Fecha de emisión
Abr 29, 2017
Derivatives center on the idea of change in an instant, but change happens across time while an instant consists of just one moment. How does that work?
2017x6
Derivative formulas through geometry | Essence of calculus, chapter 3
Episode overview
Fecha de emisión
Abr 30, 2017
A few derivative formulas, such as the power rule and the derivative of sine, demonstrated with geometric intuition.

Visualizing the chain rule and product rule | Essence of calculus, chapter 4
Episode overview
Fecha de emisión
May 01, 2017
A visual explanation of what the chain rule and product rule are, and why they are true.

What's so special about Euler's number e? | Essence of calculus, chapter 5
Episode overview
Fecha de emisión
May 02, 2017
A visual explanation of what the chain rule and product rule are, and why they are true.
2017x9
Implicit differentiation, what's going on here? | Essence of calculus, chapter 6
Episode overview
Fecha de emisión
May 03, 2017
Implicit differentiation can feel weird, but what's going on makes much more sense once you view each side of the equation as a two-variable function, f(x, y).
2017x10
Limits, L'Hopital's rule, and epsilon delta definitions | Essence of calculus, chapter 7
Episode overview
Fecha de emisión
May 04, 2017
Formal derivatives, the epsilon-delta definition, and why L'Hôpital's rule works.

May 05, 2017
What is an integral? How do you think about it?
2017x12
What does area have to do with slope? | Essence of calculus, chapter 9
Episode overview
Fecha de emisión
May 06, 2017
Integrals are used to find the average of a continuous variable, and this can offer a perspective on why integrals and derivatives are inverses, distinct from the one shown in the last video.
2017x13
Higher order derivatives | Essence of calculus, chapter 10
Episode overview
Fecha de emisión
May 07, 2017
A very quick primer on the second derivative, third derivative, etc.
