  2. Runge–Kutta–Fehlberg method - Wikipedia

    en.wikipedia.org/wiki/Runge–Kutta–Fehlberg...

    The solution is the weighted average of six increments, where each increment is the product of the size of the interval, , and an estimated slope specified by function f on the right-hand side of the differential equation.

  3. Logistic map - Wikipedia

    en.wikipedia.org/wiki/Logistic_map

    The reason that the dyadic transformation is also called the bit-shift map is that when y is written in binary notation, the map moves the binary point one place to the right (and if the bit to the left of the binary point has become a "1", this "1" is changed to a "0"). A cycle of length 3, for example, occurs if an iterate has a 3-bit ...

  4. Plane wave expansion method - Wikipedia

    This can be solved by building a matrix for the terms in the left hand side, and finding its eigenvalue and vectors. The eigenvalues correspond to the modal solutions, while the corresponding magnetic or electric fields themselves can be plotted using the Fourier expansions.

    A sample solution in the Lorenz attractor when ρ = 28, σ = 10, and β = ⁠ 8 / 3 ⁠. The Lorenz system is a system of ordinary differential equations first studied by mathematician and meteorologist Edward Lorenz.

  7. Bézier curve - Wikipedia

    en.wikipedia.org/wiki/Bézier_curve

    With reference to the figure on the right, the important features of the parabola can be derived as follows: [13] Tangents to the parabola at the endpoints of the curve (A and B) intersect at its control point (C). If D is the midpoint of AB, the tangent to the curve which is perpendicular to CD (dashed cyan line) defines its vertex (V). Its ...

    en.wikipedia.org/wiki/Body_relative_direction

    A non-flipped image of a right-handed Cartesian coordinate system, illustrating the x (right-left), y (forward-backward) and z (up-down) axes relative to a human being.Body relative directions (also known as egocentric coordinates) [1] are geometrical orientations relative to a body such as a human person's body or a road sign.

  9. Mandelbrot set - Wikipedia

    en.wikipedia.org/wiki/Mandelbrot_set

    The Mandelbrot set within a continuously colored environment. The Mandelbrot set (/ ˈ m æ n d əl b r oʊ t,-b r ɒ t /) [1] [2] is a two-dimensional set with a relatively simple definition that exhibits great complexity, especially as it is magnified.
