The Riemann zeta function. This is one of those objects in modern math that a lot of you might have heard of, but which can be really difficult to understand. Don’t worry, I’ll explain that animation that you just saw in a few minutes. A lot of people know about this function because there’s a…

## Continuous, Discontinuous, and Piecewise Functions

It’s Professor Dave, let’s learn about continuity in functions. We’ve just learned about a variety of functions, and up until now, they have all been continuous functions. These are functions where there are no gaps whatsoever. Any X value can act as an input, and we get all the corresponding values for the function as…

## The Composition of Two Functions 143-2.6.2.a

This video is provided as supplementary material for courses taught at Howard Community College and in this video I want to talk about the composition of functions. Let’s say you’re given two functions. You’ve got function f, and this is f(x)=x + 3, and function g, and that’s g(x)=x^2 – 5. and then you’re told…

## The Mathematics of Poetry

Poetry and Math was always a paradox. We wanted to break down the differences between the two and show that actually there’s a lot of similarities A lot of the kinds of questions that are on the table for poetry are also on the table for mathematicians Poetry is all about creativity and Maths is…

## Derivatives of Composite Functions: The Chain Rule

Professor Dave here, let’s learn the chain rule. We know how to take derivatives of polynomials in standard form, trigonometric functions, as well as simple products and quotients of these functions. But unfortunately, functions can get more complicated than this. What if we have a trinomial raised to an exponent? Or a trig function operating…

## Faster than a calculator | Arthur Benjamin | TEDxOxford

Translator: Mohammed Basheer Reviewer: Nadine Hennig Good afternoon, ladies and gentlemen, my name is Art Benjamin and I am a “mathemagician”. What that means is I combine my loves of math – or I should say maths – and magic to do what I call “mathemagics”. But before I get started, I’ve got a quick…

## unit 3 test corrections 7 Derivative of absolute value functions

Right let’s take a look at question number seven we are to find F prime if F is the absolute value of three X plus two okay so there two possible solutions you can have for this the derivative of this function so the first one I’m going to be using the differentiation rule DDX…

## Math is the hidden secret to understanding the world | Roger Antonsen

Hi. I want to talk about understanding, and the nature of understanding, and what the essence of understanding is, because understanding is something we aim for, everyone. We want to understand things. My claim is that understanding has to do with the ability to change your perspective. If you don’t have that, you don’t have…
