Tschebyscheff theorem
WebThe Chebyshev polynomials are two sequences of polynomials related to the cosine and sine functions, notated as () and ().They can be defined in several equivalent ways, one of which starts with trigonometric functions: . The Chebyshev polynomials of the first kind are defined by () = ().Similarly, the Chebyshev polynomials of the second kind are defined by Web1. Let k≥1. Show that, for any set of n measurements, the fraction included in the interval y ¯ − k s to y ¯ + k s is at least ( 1 − 1 / k 2). This result is known as Tchebysheff's theorem. …
