Pi The number π is a mathematical constant, the ratio of a circle's circumference to its diameter, approximately equal to 3.14159. It has been represented by the Greek letter "π" since the mid-18th century though it is also sometimes spelled out as "pi" (/paɪ/). Being an irrational number, π cannot be expressed exactly as a common fraction. Fractions such as 22/7 and other rational numbers are commonly used to approximate π. For thousands of years mathematicians have attempted to extend their understanding of π, sometimes by computing its value to a high degree of accuracy. Because its definition relates to the circle, π is found in many formulae in trigonometry and geometry, especially those concerning circles, ellipses or spheres. Fundamentals Name The symbol used by mathematicians to represent the ratio of a circle's circumference to its diameter is the Greek letter π, sometimes spelled out as pi, particularly when foreign fonts are not available.

Pi Draw a circle with a diameter (all the way across the circle) of 1 Then the circumference (all the way around the circle) is 3.14159265... a number known as Pi Pi is often written using the greek symbol π The definition of π is: The Circumference divided by the Diameter of a Circle. To help you remember what π is ... just draw this diagram. Finding Pi Yourself Draw a circle, or use something circular like a plate. Measure around the edge (the circumference): I got 82 cm Measure across the circle (the diameter): I got 26 cm Divide: 82 cm / 26 cm = 3.1538... That is pretty close to π. Using Pi We can use π to find a Circumference when we know the Diameter Circumference = π × Diameter Example: You walk around a circle which has a diameter of 100 m, how far have you walked? Distance walked = Circumference = π × 100 m = 314.159... m = 314 m (to the nearest m) Also we can use π to find a Diameter when we know the Circumference Diameter = Circumference / π Diameter = Circumference / π = 94 mm / π = 29.92... mm Radius

Complex Fractions: More Examples Complex Fractions: More Examples (page 2 of 2) Simplify the following expression: Can I start by hacking off the x – 3's? Clearly, nothing cancels, so my final answer is: (Why the restrictions?) It is highly unusual for a complex fraction to simplify this much, but it can happen. I can only cancel factors, not terms, so the above cancellations are not proper. Then my final answer is: Copyright © Elizabeth Stapel 2003-2011 All Rights Reserved (Why the restrictions?) Simplify the following expression: Can I start by canceling off the 1's or the 1/t's? Can I cancel off the t's now? (Why the restrictions?) When working with complex fractions, be careful to show each step completely. << Previous Top | 1 | 2 | Return to Index

Pythagorean Theorem and its many proofs Professor R. Smullyan in his book 5000 B.C. and Other Philosophical Fantasies tells of an experiment he ran in one of his geometry classes. He drew a right triangle on the board with squares on the hypotenuse and legs and observed the fact the the square on the hypotenuse had a larger area than either of the other two squares. Then he asked, "Suppose these three squares were made of beaten gold, and you were offered either the one large square or the two small squares. Which would you choose?" The Pythagorean (or Pythagoras') Theorem is the statement that the sum of (the areas of) the two small squares equals (the area of) the big one. In algebraic terms, a² + b² = c² where c is the hypotenuse while a and b are the legs of the triangle. The theorem is of fundamental importance in Euclidean Geometry where it serves as a basis for the definition of distance between two points. Below is a collection of 118 approaches to proving the theorem. Remark Proof #1 First of all, ΔABF = ΔAEC by SAS. or

Lessons | Passy's World of Mathematics | Mathematics Help Online | Page 5 Image Source: WordPress.com A survey was conducted at a Cafe which sells food and coffees. The reason for the survey was that they were having trouble keeping up with the demand for Cappuccino coffees during peak periods. The Barista suggested that they get a bigger machine to cope with the high demand. A bigger machine is very expensive to buy, and so the owner had a two day survey done to find out how many Cappuccinos were being made per hour in the Cafe. From the survey results, they would be able to do some Graphs and Statistics, and better understand the current problem situation. Gathering and Analysing Statistical Data is a key part of Business and Marketing, and provides a mathematical picture of current situations and future initiatives. In this lesson we look at finding the Mean, Median, and Mode Averages for Grouped Data containing Class Intervals. The Modal Class
