  2. Completing the square - Wikipedia

    en.wikipedia.org/wiki/Completing_the_square

    That is, h is the x-coordinate of the axis of symmetry (i.e. the axis of symmetry has equation x = h), and k is the minimum value (or maximum value, if a < 0) of the quadratic function. One way to see this is to note that the graph of the function f ( x ) = x 2 is a parabola whose vertex is at the origin (0, 0).

  3. Quadratrix of Hippias - Wikipedia

    en.wikipedia.org/wiki/Quadratrix_of_Hippias

    If one places such a square with side length in a (Cartesian) coordinate system with the side ¯ on the -axis and with vertex at the origin, then the quadratix is described by a planar curve : (,] with = (() ()) = (⁡ ()) This description can also be used to give an analytical rather than a geometric definition of the quadratrix and to extend ...

  4. Quadratic equation - Wikipedia

    en.wikipedia.org/wiki/Quadratic_equation

    For the quadratic function y = x 2 − x − 2, the points where the graph crosses the x-axis, x = −1 and x = 2, are the solutions of the quadratic equation x 2 − x − 2 = 0. The process of completing the square makes use of the algebraic identity + + = (+), which represents a well-defined algorithm that can be used to solve any quadratic ...

  5. 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.

    en.wikipedia.org/wiki/Gantt_chart

    This chart lists the tasks to be performed on the vertical axis, and time intervals on the horizontal axis. [4] [7] The width of the horizontal bars in the graph shows the duration of each activity. [7] [8] Gantt charts illustrate the start and finish dates of the terminal elements and summary elements of a project. [1]

    en.wikipedia.org/wiki/Translation_of_axes

    For an xyz-Cartesian coordinate system in three dimensions, suppose that a second Cartesian coordinate system is introduced, with axes x', y' and z' so located that the x' axis is parallel to the x axis and h units from it, the y' axis is parallel to the y axis and k units from it, and the z' axis is parallel to the z axis and l units from it.
