## Finding Minimums and Maximums using a Graphing Calculator

While it is important to be able to find minimums and maximums of an equation algebraically, using a graphing calculator, it is much easier to find these.  Any equation where one can isolate the y variable can be graphed on…

## Using a Graphing Calculator to Solve a System of Equations

Solving a system of equations can be difficult for those who are just starting out.  However, with a graphing calculator, solving these becomes much easier.  In order to do this, one must first understand that an equation in two variable…

## Relationship between p value and Confidence

Are there really lies, damned lies and statistics? You don’t need to get bogged down in mathematics to answer that. You just need to understand the logic behind probability tests, p-values and Confidence Intervals. All conventional statistical tests of probability…

## Cantors Infinity Proof Made Easy

Infinity is a concept that grabs the human imagination. There is something both fascinating and futile about the realisation that no matter how large a number you think of, there is always a larger one. You can never, ever reach…

## An Introduction Quadrilaterals

Let’s get to know our four-sided friends. Sure enough, the quadrilateral is named quite literally. That’s “quad” for four, and “lateral” for side. (You didn’t think football players made up the word, did you?) But to make sure that everyone…

## Understanding the Mathematical Subject Plane Geometry

Plane geometry consists of straight lines, points, and curved lines in a plane.A plane is a two-dimensional object that is an infinite square composed ofall the points within the square. A point has zero dimensions. One postulate ofgeometry states that…

## Understanding Squares

In geometry, a square is defined as a shape with four sides the same length (and with each side at a 90 degree angle to the others). But squares are very simple, which makes them a great way to start…

## The Usefulness of Applied Mathematics

To understand the usefulness of “applied mathematics,” one needs to know what that simply means.This is the type of mathematics that uses the abstract to solve concrete problems in sciences, businesses, and other areas. In short, applied mathematics is “social…

## Probability in Games of Chance

Understanding probability is crucial to winning at games of chance, or at the very least understanding that you won’t be winning long-term. What games does probability have practical applications in? 1. Poker- Poker is one of the few games of…

## Division by zero the Quest for a Mathematical Proof of God

“Dr James Anderson, a computer science professor at the University of Reading (UK) earned a bit of fame and notoriety in 2006 by claiming he had solved, “a 1200 year old problem,” most notably, he offered a proof that division…
