  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 ...

    Right-click on the graph and select "Export" → "Encapsulated Postscript" from the menu which appears. Choose a file name to save the graph as. In Inkscape, import the graph using "File" → "Import...". After importing, select "File" → "Document Properties..." and click "Fit page to selection". Save the SVG file and upload it.

  5. Sides of an equation - Wikipedia

    Similarly, RHS is the right-hand side. The two sides have the same value, expressed differently, since equality is symmetric. [1] More generally, these terms may apply to an inequation or inequality; the right-hand side is everything on the right side of a test operator in an expression, with LHS defined similarly.

  6. 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.

  7. Geometric Brownian motion - Wikipedia

    For the simulation generating the realizations, see below. A geometric Brownian motion (GBM) (also known as exponential Brownian motion) is a continuous-time stochastic process in which the logarithm of the randomly varying quantity follows a Brownian motion (also called a Wiener process) with drift. [1]

  8. Lorenz system - Wikipedia

    en.wikipedia.org/wiki/Lorenz_system

    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.

  9. Asymptotic expansion - Wikipedia

    en.wikipedia.org/wiki/Asymptotic_expansion

    Here, the right hand side is clearly not convergent for any non-zero value of t. However, by truncating the series on the right to a finite number of terms, one may obtain a fairly good approximation to the value of Ei ⁡ ( 1 t ) {\displaystyle \operatorname {Ei} \left({\tfrac {1}{t}}\right)} for sufficiently small t .
