It is impossible to arrive at an exact value for pi because the digits that make up its decimal neither end nor repeat, according to Scientific American. It is therefore an irrational number, and the closest value that can be asserted is an approximation.
Continue ReadingShigeru Kondo, a Japanese systems engineer, and Alexander Yee, a U.S. computer scientist, collaborated to build a special computer that took over a year to calculate pi to the 10 trillionth digit. Extensive calculations of this sort are useful for testing the integrity of supercomputers and highly precise multiplication algorithms, but generally speaking, most scientific applications require no more than 40 decimal places.

This approach is vital to understanding what exactly is being asked.
Full Answer >A limit solver is tool that can determine the limit of a function when a variable approaches a given value. As of August 2014, limit solvers are available online at WolframAlpha, Symbolab and MathPortal.
Full Answer >Recursive formulas have two parts: the first element and a formula relating the value of one element to the next. For example, in the sequence "1, 3, 5, 7, 9, ..." the first element is 1; the formula is the current element equals the last element plus two.
Full Answer >Find the mean absolute deviation by finding the sum of the absolute value of x minus mu, all divided by N. In this formula, mu is the mean, x is the value of the term and N is the total number of terms.
