Orthogonal polynomials

In mathematics, a sequence of orthogonal polynomials is called a sequential sequence of real polynomials where each polynomial has degree n, and also two different polynomials of this other are orthogonal to each other in some sense of the scalar product defined in the space The concept of orthogonal polynomials was introduced at the end of the 19th century. in the works of P.L. Chebyshev on continued fractions and later developed by A.A. Markov and T.I. Stieltjes and found various applications in many areas of mathematics and physics.
