Topology for Mr. Freedland

Doughnut shaped graphs appear in a branch of mathematics called topology. It is a class that is generally offered at a graduate level. That means after you graduate from college with your bachelors degree and decide to go back and get a masters in mathematics. If you want to learn more about topology then AWESOME, but I'd advise you to fine tune your algebra skills first.;)

The Quadratic Formula

What is the quadratic formula you may ask? The first 3 students to tell me why the Quadratic Equation is useful will get 1 bonus point on their class test or an extra bathroom pass, your choice... (You may not think it's much, but it could be the difference between a 92 or a 93.)

Fractal Math?

The process of generating this fractal is based on an extremely simple equation involving complex (imaginary) numbers. This is an example of the Mandelbrot Set. It is an infinite pattern.

Imaginary Schminaginary

Real numbers are the numbers that you probably already know: they're the ones on the number line. Contrary to what some people might tell you though, imaginary numbers, are not numbers that only exist in the brains of weird people. Or maybe they are; all numbers in math are "imaginary" in the sense that you can't touch them or experience them directly. But this is not what people mean when they talk about imaginary numbers. Imaginary numbers are numbers that can be written as a real number times i or a + bi. So, what is i? It's the square root of -1. i is NOT a real number. i was invented because mathematicians wanted to do more math and not have to stop when they had to take square roots of negative numbers.

Rene Descartes (DAY-CART) was the first to use the term “imaginary” number in 1637. However, imaginary numbers were discovered much earlier by Gerlamo Cardono in the 1500s but they were not widely accepted until the work of Leonhard Euler (1707–1783 ) and Carl Friedrich Johan Gauss (177 7–1855).

Green is the New Black

Over 30 teachers at Hoggard High School are interested in placing a recycling bin in their classroom! We've received cash donations as well! The best way you can help is to donate a recycle bin. Juniors and Seniors donating a recycle bin will receive one service point for a donation. Bins that are 18-gallons or larger will work best. (With a lid that we can cut a hole in for cans and bottles). Beta Club members and staff who would like to participate should see Mr. Jupena in room 201 as soon as possible. Do you have access to a truck or van? Are you willing to empty the bins at the drop-off site? WE NEED YOU!

Kermit the Frog once said "It ain't easy being green," but Hoggard HS will be greener if we all pitch in a little. Thanks for your help in saving the world!
