Theorems about triangles and circles

Harcourt's theorem

Harcourt's theorem is a formula in geometry for the area of a triangle, as a function of its side lengths and the perpendicular distances of its vertices from an arbitrary line tangent to its incircle. The theorem is named after J. Harcourt, an Irish professor. (Wikipedia).

Big Data is a Hotbed of Thoughtcrime, Part II: The Code - Jim Adler

At Strata 2012 in New York, we discussed the hazards of curbing big data inferences by defining a new category of thoughtcrime. After all, acting on thoughts might constitute a crime, but thoughts, in isolation, cannot be criminal. It's time to go deeper. Let's create and evaluate a predic

Calculus - Find the limit of a function using epsilon and delta

This video shows how to use epsilon and delta to prove that the limit of a function is a certain value. This particular video uses a linear function to highlight the process and make it easier to understand. Later videos take care of more complicated functions and using epsilon and delta
