  2. Solving quadratic equations with continued fractions

    en.wikipedia.org/wiki/Solving_quadratic...

    If the discriminant is zero the fraction converges to the single root of multiplicity two. If the discriminant is positive the equation has two real roots, and the continued fraction converges to the larger (in absolute value) of these. The rate of convergence depends on the absolute value of the ratio between the two roots: the farther that ...

    The q-line (depicted in blue in Figure 1) intersects the point of intersection of the feed composition line and the x = y line and has a slope of q / (q - 1), where the parameter q denotes mole fraction of liquid in the feed. For example, if the feed is a saturated liquid, q = 1 and the slope of the q-line is infinite (drawn as a vertical line).

    en.wikipedia.org/wiki/Equation_solving

    An example of using Newton–Raphson method to solve numerically the equation f(x) = 0. In mathematics, to solve an equation is to find its solutions, which are the values (numbers, functions, sets, etc.) that fulfill the condition stated by the equation, consisting generally of two expressions related by an equals sign.

  5. Quartic equation - Wikipedia

    en.wikipedia.org/wiki/Quartic_equation

    In mathematics, a quartic equation is one which can be expressed as a quartic function equaling zero. The general form of a quartic equation is Graph of a polynomial function of degree 4, with its 4 roots and 3 critical points. + + + + = where a ≠ 0.

  6. Continued fraction - Wikipedia

    In the first of these equations the ratio tends toward ⁠ A n / B n ⁠ as z tends toward zero. In the second, the ratio tends toward ⁠ A n / B n ⁠ as z tends to infinity. This leads us to our first geometric interpretation. If the continued fraction converges, the successive convergents ⁠ A n / B n ⁠ are eventually arbitrarily close ...

    Later on, the text can refer to this equation by its number using syntax like this: As seen in equation ({{EquationNote|1}}), example text... The result looks like this: As seen in equation , example text... The equation number produced by {{EquationNote}} is a link that the user can click to go immediately to the cited equation.

  9. Periodic continued fraction - Wikipedia

    en.wikipedia.org/wiki/Periodic_continued_fraction

    By considering the complete quotients of periodic continued fractions, Euler was able to prove that if x is a regular periodic continued fraction, then x is a quadratic irrational number. The proof is straightforward. From the fraction itself, one can construct the quadratic equation with integral coefficients that x must satisfy.
