  2. Symbolab - Wikipedia

    en.wikipedia.org/wiki/Symbolab

    Symbolab is an answer engine [1] that provides step-by-step solutions to mathematical problems in a range of subjects. [2] It was originally developed by Israeli start-up company EqsQuest Ltd., under whom it was released for public use in 2011. In 2020, the company was acquired by American educational technology website Course Hero. [3] [4]

  3. Difference engine - Wikipedia

    en.wikipedia.org/wiki/Difference_engine

    The name difference engine is derived from the method of finite differences, a way to interpolate or tabulate functions by using a small set of polynomial co-efficients. Some of the most common mathematical functions used in engineering, science and navigation are built from logarithmic and trigonometric functions , which can be approximated by ...

  4. Quadratic equation - Wikipedia

    Figure 4. Graphing calculator computation of one of the two roots of the quadratic equation 2x 2 + 4x − 4 = 0. Although the display shows only five significant figures of accuracy, the retrieved value of xc is 0.732050807569, accurate to twelve significant figures. A quadratic function without real root: y = (x − 5) 2 + 9.

  5. Degree of a polynomial - Wikipedia

    This should be distinguished from the names used for the number of variables, the arity, which are based on Latin distributive numbers, and end in -ary. For example, a degree two polynomial in two variables, such as x 2 + x y + y 2 {\displaystyle x^{2}+xy+y^{2}} , is called a "binary quadratic": binary due to two variables, quadratic due to ...

    en.wikipedia.org/wiki/Pentagon

    The Carlyle circle was invented as a geometric method to find the roots of a quadratic equation. [5] This methodology leads to a procedure for constructing a regular pentagon. The steps are as follows: [6] Draw a circle in which to inscribe the pentagon and mark the center point O. Draw a horizontal line through the center of the circle.

  7. 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.

  8. Quadrilateral - Wikipedia

    en.wikipedia.org/wiki/Quadrilateral

    Formulas to compute its dihedral angles from the edge lengths and the angle between two adjacent edges were derived for work on the properties of molecules such as cyclobutane that contain a "puckered" ring of four atoms. [55] Historically the term gauche quadrilateral was also used to mean a skew quadrilateral. [56]

  9. Quadratic function - Wikipedia

    en.wikipedia.org/wiki/Quadratic_function

    In mathematics, a quadratic function of a single variable is a function of the form [1] = + +,,where ⁠ ⁠ is its variable, and ⁠ ⁠, ⁠ ⁠, and ⁠ ⁠ are coefficients.The expression ⁠ + + ⁠, especially when treated as an object in itself rather than as a function, is a quadratic polynomial, a polynomial of degree two.
