  2. Gauss's method - Wikipedia

    en.wikipedia.org/wiki/Gauss's_method

    NOTE: Gauss's method is a preliminary orbit determination, with emphasis on preliminary. The approximation of the Lagrange coefficients and the limitations of the required observation conditions (i.e., insignificant curvature in the arc between observations, refer to Gronchi [ 2 ] for more details) causes inaccuracies.

  3. Roth IRA - Wikipedia

    en.wikipedia.org/wiki/Roth_IRA

    A Roth IRA is an individual retirement account (IRA) under United States law that is generally not taxed upon distribution, provided certain conditions are met. The principal difference between Roth IRAs and most other tax-advantaged retirement plans is that rather than granting an income tax reduction for contributions to the retirement plan, qualified withdrawals from the Roth IRA plan are ...

    For example, to solve a system of n equations for n unknowns by performing row operations on the matrix until it is in echelon form, and then solving for each unknown in reverse order, requires n(n + 1)/2 divisions, (2n 3 + 3n 2 − 5n)/6 multiplications, and (2n 3 + 3n 2 − 5n)/6 subtractions, [10] for a total of approximately 2n 3 /3 operations.

    In numerical analysis Gauss–Laguerre quadrature (named after Carl Friedrich Gauss and Edmond Laguerre) is an extension of the Gaussian quadrature method for approximating the value of integrals of the following kind: + (). In this case

  9. Gauss–Legendre method - Wikipedia

    en.wikipedia.org/wiki/Gauss–Legendre_method

    Gauss–Legendre methods are implicit Runge–Kutta methods. More specifically, they are collocation methods based on the points of Gauss–Legendre quadrature. The Gauss–Legendre method based on s points has order 2s. [1] All Gauss–Legendre methods are A-stable. [2] The Gauss–Legendre method of order two is the implicit midpoint rule.
