##### Mathematical constant
From Wikipedia, the free encyclopedia Jump to: navigation search A mathematical constant is a special number, usually a real number , that arises naturally in mathematics . Unlike physical constants , mathematical constants are defined independently of physical measurement. Some mathematical constants, such as e and , arise in many different contexts. Others, such as Graham's number or Skewes' number , only arise in a single specific context, but are notable because they are the earliest found, largest or smallest exemplar of a class of numbers. Many of the more interesting mathematical constants have a name, also when they can easily be specified by a short formula. What it means for a constant to arise "naturally", and what makes a constant "interesting", is ultimately a matter of taste, and some mathematical constants are notable more for historical reasons than for their intrinsic mathematical interest. Mathematical constants are always definable numbers and are almost always also computable numbers Chaitin's constant being a significant exception). However, computable constants need not be easily computed; the

 Algebra Applied Mathematics Calculus and Analysis Discrete Mathematics ... Interactive Demonstrations Constant A constant, sometimes also called a "mathematical constant," is any well-defined real number which is significantly interesting in some way. In this work, the term "constant" is generally reserved for real nonintegral numbers of interest, while " number " is used to refer to interesting integers (e.g., Brun's constant , but beast number ). However, in contexts such as linear combination , the term "constant" is generally used to mean " scalar " or " real number ," and need not exclude integer values. A function, equation, etc., is said to "be constant" (or be a constant function ) if it always assumes the same value independent of how its parameters are varied. Certain constants are known to many decimal digits and recur throughout many diverse areas of mathematics, often in unexpected and surprising places (e.g., pi e , and to some extent, the Euler-Mascheroni constant ). Other constants are more specialized and may be known to only a few

 Mathematical Constants This is the most well known mathematical constant, and is the ratio of the circumference of a circle to its diameter - the fact that this is the same for all circles is amazing in itself. The value has been estimated since biblical times, Pi through the ages , and a (wrong) value was almost written into a law You will know that can be approximated by which only gives the value correct to 2 decimal places. is correct to 6 decimal places, and to 9 decimal places. has been calculated to over 50 billion digits . See Table of current records for the computation of constants for the current record for and other constants. is not only irrational (it cannot be written exactly as the ratio of two integers) it is also transcendental (it is not the solution of any polynomial equation with rational coefficients). You will find proofs in Transcendence of Pi and in T E X format Not many transcendental numbers are known ( e and Liouville's number are another two examples) but in fact in 1874 Cantor showed that almost all real numbers are transcendental. You can see some of the proofs if you follow the links at

Print-friendly page Variation Equations (page 1 of 3) Variation problems aren't hard once you get the hang of the lingo. The only real difficulty is learning the somewhat specialized vocabulary and the techniques for this classification of problems. Variation problems involve fairly simple relationships or formulas, involving one variable being equal to one term. That term might be linear (something with just an " x "), quadratic (something in " x "), more than one variable (such as " r h "), a square root (something like " "), or something else. But it is always just the one term in the formula, multiplied by some number, usually denoted by " k " if you don't yet know the number's value; this number

http://www.ndt-ed.org/EducationResources/Math/Math-e.htm
 Home Education Resources What is e? e is usually defined by the following equation: Its value is approximately 2.718 and has been calculated to 869,894,101 decimal places by Sebastian Wedeniwski. The number e was first studied by the Swiss mathematician Leonhard Euler in the 1720s, although its existence was more or less implied in the work of John Napier, the inventor of logarithms, in 1614. Euler was also the first to use the letter e for it in 1727 (the fact that it is the first letter of his surname is coincidental). As a result, sometimes e is called the Euler Number, the Eulerian Number, or Napier's Constant. It was proven by Euler that "e" is an irrational number, so its decimal expansion never terminates, nor is it ever periodic. An effective way to calculate the value of e is not to use the defining equation above, but to use the following infinite sum of factorials. Factorials are just products of numbers indicated by an exclamation mark. For instance, "four factorial" is written as "4!" and means 1×2×3×4 = 24.

##### Learning about Rate of Change in Linear Functions Using Interactive Graphs : Constant Cost per Minute
Constant Cost per Minute
Changing Cost per Minute In this two-part example, users can drag a slider on an interactive graph to modify a rate of change (cost per minute for phone use) and learn how modifications in that rate affect the linear graph displaying accumulation (the total cost of calls). In this first part, Constant Cost per Minute, the cost per minute for phone use remains constant over time. In the second part, Changing Cost per Minute, the cost per minute for phone use changes after the first sixty minutes of calls. Understanding the relationship between change and accumulation is a precursor to understanding calculus. This example illustrates the use of dynamic graphs to learn about change and linear relationships, as described in the Algebra Standard
