  • 6: 37.2 General Orthogonal Polynomials of Two Variables
    In this section polynomials will be polynomials of two variables with real coefficients. …Then …Then dim 𝒱 n = n + 1 . … One of the OPs resulting from this classification are the Hahn polynomials of two variables, see §37.10(iv).

    With appropriate scalings, Newton’s equation of motion for a pendulum with a mass in a gravitational field constrained to move in a vertical plane at a fixed distance from a fulcrum is … Classical motion in one dimension is described by Newton’s equation … Two types of oscillatory motion are possible. For an initial displacement with 1 / β | a | < 2 / β , bounded oscillations take place near one of the two points of stable equilibrium x = ± 1 / β . … Whittaker (1964, Chapter IV) enumerates the complete class of one-body classical mechanical problems that are solvable this way. …
