Continued fractions can also be applied to problems in number theory, and are especially useful in the study of Diophantine equations. In the late eighteenth century Lagrange used continued fractions to construct the general solution of Pell's equation, thus answering a question that had fascinated mathematicians for more than a thousand years.

The theorem states that for almost all real numbers in the interval (0,1), the number of terms m of the number's continued fraction expansion that are required to determine the first n places of the number's decimal expansion behaves asymptotically as follows:
Euler derived the formula as connecting a finite sum of products with a finite continued fraction. (+ (+ (+))) = + + + + = + + + +The identity is easily established by induction on n, and is therefore applicable in the limit: if the expression on the left is extended to represent a convergent infinite series, the expression on the right can also be extended to represent a convergent infinite ...

E. coli's presence can be caused by increased run-off from heavy rains or a break in pipes or water treatment. It usually indicates human or animal waste contamination.
What is E. coli? Two of nine samples from two municipal systems, the Main and Village Green water systems, tested positive for E. coli, a bacteria that can indicate fecal contamination.
The presence of E. coli indicates the water may be contaminated by human or animal wastes, including fecal matter. The presence results from problems with the treatment process or pipes in a water ...
The golden ratio φ is the irrational number with the very simplest possible expansion as a regular continued fraction: φ = [1; 1, 1, 1, …]. The theorem tells us first that if x is any real number whose expansion as a regular continued fraction contains the infinite string [1, 1, 1, 1, …], then there are integers a , b , c , and d (with ad ...
