Something Fishy about the Vesica Piscis: Area of a Cat's Pupil - Geometry Kit Series - Episode 2

Charis doesn't fare better than Adam with the Geometry Kit. Adam finds other options. Colourful depictions of Euclid's First Proposition. Stuff about fish and religion. It all makes sense. Honest. More about Euclid's first proposition: https://mathcs.clarku.edu/~djoyce/elements/bookI/prop

Vector form of multivariable quadratic approximation

This is the more general form of a quadratic approximation for a scalar-valued multivariable function. It is analogous to a quadratic Taylor polynomial in the single-variable world.

The Meaning of Pi

More important than knowing a bunch of digits in the decimal approximation of Pi is to understand what Pi means. Pi is the ratio of the Circumference to the Diameter of any circle. Multiply the diameter by Pi to get the circumference or divide the circumference by pi to get the diameter.

Defining Pi for Physics

Pi is defined as the ratio of the circumference of a circle to its diameter. A frisbee is used to show the definition of pi. The units for pi, radians, are discussed. The conversion factor between revolutions, degrees, and radians is introduced. Want Lecture Notes? http://www.flippingphysi

How to solve differentiable equations with logarithms

Learn how to solve the particular solution of differential equations. A differential equation is an equation that relates a function with its derivatives. The solution to a differential equation involves two parts: the general solution and the particular solution. The general solution give
