  2. Chebyshev polynomials - Wikipedia

    en.wikipedia.org/wiki/Chebyshev_polynomials

    The Chebyshev polynomials of the second kind are defined by the recurrence relation: = = + = (). Notice that the two sets of recurrence relations are identical, except for () = vs. () =.

  3. Recurrence relation - Wikipedia

    en.wikipedia.org/wiki/Recurrence_relation

    In mathematics, a recurrence relation is an equation according to which the th term of a sequence of numbers is equal to some combination of the previous terms. Often, only previous terms of the sequence appear in the equation, for a parameter that is independent of ; this number is called the order of the relation.

  4. Orthogonal polynomials - Wikipedia

    en.wikipedia.org/wiki/Orthogonal_polynomials

    The Gegenbauer polynomials form the most important class of Jacobi polynomials; they include the Chebyshev polynomials, and the Legendre polynomials as special cases. The field of orthogonal polynomials developed in the late 19th century from a study of continued fractions by P. L. Chebyshev and was pursued by A. A. Markov and T. J. Stieltjes.

  5. Chebyshev nodes - Wikipedia

    en.wikipedia.org/wiki/Chebyshev_nodes

    The Chebyshev nodes of the second kind, also called the Chebyshev extrema, are the extrema of the Chebyshev polynomials of the first kind, which are also the zeros of the Chebyshev polynomials of the second kind. Both of these sets of numbers are commonly referred to as Chebyshev nodes in literature. [1] Polynomial interpolants constructed from ...

  6. Chebyshev equation - Wikipedia

    en.wikipedia.org/wiki/Chebyshev_equation

    Chebyshev 's equation is the ... where the coefficients obey the recurrence relation ... that function is a polynomial of degree p and it is proportional to the ...

  7. Classical orthogonal polynomials - Wikipedia

    en.wikipedia.org/wiki/Classical_orthogonal...

    Because of this, expansion of functions in terms of Chebyshev polynomials is sometimes used for polynomial approximations in computer math libraries. Some authors use versions of these polynomials that have been shifted so that the interval of orthogonality is [0, 1] or [−2, 2].

  8. Fibonacci polynomials - Wikipedia

    en.wikipedia.org/wiki/Fibonacci_polynomials

    In mathematics, the Fibonacci polynomials are a polynomial sequence which can be considered as a generalization of the Fibonacci numbers. The polynomials generated in a similar way from the Lucas numbers are called Lucas polynomials .

  9. Clenshaw algorithm - Wikipedia

    en.wikipedia.org/wiki/Clenshaw_algorithm

    The recurrence relation for ⁡ is ⁡ (+) = ⁡ ⁡ ⁡ (), making the coefficients in the recursion relation = ⁡, = and the evaluation of the series is given by + = + =, = + ⁡ + + (), The final step is made particularly simple because () = ⁡ =, so the end of the recurrence is simply () ⁡ (); the term is added separately: = + ⁡.
