Celebrate Pi Day Every year math enthusiasts everywhere celebrate pi, a celebrity among mathematical constants, on March 14 (3/14), also known as Pi Day. Extreme enthusiasts have a special celebration at 1:59 (aka, Pi Minute). Pi is the symbol for the ratio of the circumference of a circle to its diameter. Whatever the size of a circle, if you divide its circumference by its diameter you will always get 3.14159..., better known as pi. Pi is an irrational number, continuing infinitely without repeating. Although the ratio has been around for about 4,000 years, the symbol just turned 300 years old in 2006.

19 Great Online Graphing Calculators for Teachers and Students In the old days, you were pretty much limited to a handheld graphing calculator in order to produce graphs of equations. That has all changed in the past few years with the introduction of online graphing calculators. Unfortunately, not all graphing calculators are created equal. I don’t believe there is any “best” online graphing calculator since it all depends on what you want to do with the calculator. Take a look at all these online graphing calculators that are at your disposal. Desmos Graphing Calculator–Free Graphing Calculator, by Desmos.com.

What is pi, and how did it originate? Steven Bogart, a mathematics instructor at Georgia Perimeter College, provides the following explanation: Succinctly, pi--which is written as the Greek letter for p, or --is the ratio of the circumference of any circle to the diameter of that circle. was first used for this purpose by William Jones in 1706, probably as an abbreviation of periphery, and became standard mathematical notation roughly 30 years later. Try a brief experiment: Using a compass, draw a circle. Otherwise said, if you cut several pieces of string equal in length to the diameter, you will need a little more than three of them to cover the circumference of the circle. Pi is most commonly used in certain computations regarding circles. The importance of pi has been recognized for at least 4,000 years. ," recognizing that every circle has the same ratio of circumference to diameter.

Instructions for Downloading WinPlot and Winstats Instructions for Downloading Winplot and Winstats winplot is a free graphing utility that was written by Richard Parris, a math instructor at Phillips Exeter Academy in Exeter, New Hampshire. Sadly Richard passed away in 2012. After Richard's death the program was still available for a number of years on the Exeter Academy math department's web site. Working versions of winplot and winstats (a simple to use statistical analysis package) can be intalled on a Windows operating system by right clicking on the links below. This will download a zipped version of the program to be installed on a directory of your choosing. Link to the zipped version (August, 7, 2012) of winstats: A link to a Power Point tutorial on winplot: A link to winplot files used in the calculus sequence: This page is dedicated to the memory of Richard Parris who undoubtably spent many hours in making and revising these programs for the benefit of both students and instructors.

March 14 Is Pi Day Every year on March 14, math lovers around the country celebrate pi. Some enthusiasts even go so far as to mark Pi Minute at 1:59, which takes into account the first six digits of the pi: 3.14159. Pi Day provides the perfect excuse for incorporating math and geometry into all aspects of the school day. What Is Pi? Pi is the circumference of a circle (the distance around the circle) divided by its diameter (the distance across). In other words, the circumference of any circle is approximately 3.14 times its diameter. Because pi is the same for every circle, we can use it to determine the diameter if we know the circumference, or vice versa. This gif (animated sequence) that "unrolls" pi will give your students a quick visual of how a circle’s diameter, circumference, and pi are related. The History of Pi From ancient China to Babylonia, mathematicians have been puzzling over pi for thousands of years. Fun With Pi Pi gives ample opportunity for creative math fun.

Pi Day: Pi Activities & Links Materials large sheet of drawing paper or cardboard meterstick pen toothpicks (30 or more) calculator To Do and Notice Draw a series of parallel lines on the paper or cardboard, as many as will fit, making sure that the distance between each line is exactly equal to the length of your toothpicks. Now, one by one, randomly toss toothpicks onto the lined paper. Keep tossing until you’re out of toothpicks—or tired of tossing. It’s time to count. Now use this formula to calculate an approximation of pi: Pi = 2 × (total number of toothpicks) / (number of line-crossing toothpicks) What’s Going On? The proof of why this works involves a bit of meaty math and makes a delightful diversion for those so inclined.
