  2. Bell polynomials - Wikipedia

    en.wikipedia.org/wiki/Bell_polynomials

    For instance, in the above examples, the integer 3 can be partitioned into two parts as 2+1 only. Thus, there is only one monomial in B 3,2. However, the integer 6 can be partitioned into two parts as 5+1, 4+2, and 3+3. Thus, there are three monomials in B 6,2. Indeed, the subscripts of the variables in a monomial are the same as those given by ...

  5. Estrin's scheme - Wikipedia

    en.wikipedia.org/wiki/Estrin's_scheme

    In numerical analysis, Estrin's scheme (after Gerald Estrin), also known as Estrin's method, is an algorithm for numerical evaluation of polynomials.. Horner's method for evaluation of polynomials is one of the most commonly used algorithms for this purpose, and unlike Estrin's scheme it is optimal in the sense that it minimizes the number of multiplications and additions required to evaluate ...

  6. Quadratic formula - Wikipedia

    en.wikipedia.org/wiki/Quadratic_formula

    The roots of the quadratic function y = ⁠ 1 / 2 ⁠ x 2 − 3x + ⁠ 5 / 2 ⁠ are the places where the graph intersects the x-axis, the values x = 1 and x = 5. They can be found via the quadratic formula. In elementary algebra, the quadratic formula is a closed-form expression describing the solutions of a quadratic equation.

  7. Linear equation - Wikipedia

    en.wikipedia.org/wiki/Linear_equation

    If b ≠ 0, the equation + + = is a linear equation in the single variable y for every value of x.It has therefore a unique solution for y, which is given by =. This defines a function.

    AOL may send you emails from time to time about products or features we think you'd be interested in. If you're ever concerned about the legitimacy of these emails, just check to see if there's a green "AOL Certified Mail" icon beside the sender name.

  9. Algebra - Wikipedia

    en.wikipedia.org/wiki/Algebra

    Algebra is the branch of mathematics that studies certain abstract systems, known as algebraic structures, and the manipulation of expressions within those systems. It is a generalization of arithmetic that introduces variables and algebraic operations other than the standard arithmetic operations, such as addition and multiplication.
