  2. 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.

  3. Fixed-point iteration - Wikipedia

    en.wikipedia.org/wiki/Fixed-point_iteration

    The fixed point iteration x n+1 = cos x n with initial value x 1 = −1.. An attracting fixed point of a function f is a fixed point x fix of f with a neighborhood U of "close enough" points around x fix such that for any value of x in U, the fixed-point iteration sequence , (), (()), ((())), … is contained in U and converges to x fix.

    The Riemann zeta function ζ(z) plotted with domain coloring. [1] The pole at = and two zeros on the critical line.. The Riemann zeta function or Euler–Riemann zeta function, denoted by the Greek letter ζ (), is a mathematical function of a complex variable defined as () = = = + + + for ⁡ >, and its analytic continuation elsewhere.

    en.wikipedia.org/wiki/Solve_for_X

    Solve for X was a community solution engagement project and think tank-like event launched by Google [1] to encourage collaboration, solve global issues and support innovators. The "X" in the title represents a remedy that someone or a team is already pursuing which ran from 2012 to 2014.

  8. Inverse hyperbolic functions - Wikipedia

    en.wikipedia.org/wiki/Inverse_hyperbolic_functions

    A ray through the unit hyperbola = in the point (,), where a is twice the area between the ray, the hyperbola, and the x-axis. The earliest and most widely adopted symbols use the prefix arc-: arcsinh, arccosh, arctanh, arcsech, arccsch, arccoth; by analogy with the inverse trig functions (arcsin etc.).

  9. Wave equation - Wikipedia

    en.wikipedia.org/wiki/Wave_equation

    This means that the value of v is constant on characteristic lines of the form x + ct = x 0, and thus that v must depend only on x + ct, that is, have the form H(x + ct). Then, to solve the first (inhomogenous) equation relating v to u , we can note that its homogenous solution must be a function of the form F ( x - ct ) , by logic similar to ...
