2. Rhind Mathematical Papyrus - Wikipedia

   en.wikipedia.org/wiki/Rhind_Mathematical_Papyrus

   The Rhind Mathematical Papyrus (RMP; also designated as papyrus British Museum 10057, pBM 10058, and Brooklyn Museum 37.1784Ea-b) is one of the best known examples of ancient Egyptian mathematics. It is one of two well-known mathematical papyri, along with the Moscow Mathematical Papyrus. The Rhind Papyrus is the larger, but younger, of the two..

3. Error correction code - Wikipedia

   en.wikipedia.org/wiki/Error_correction_code

   A simplistic example of ECC is to transmit each data bit 3 times, which is known as a (3,1) repetition code. Through a noisy channel, a receiver might see 8 versions of the output, see table below. Through a noisy channel, a receiver might see 8 versions of the output, see table below.

4. List of Runge–Kutta methods - Wikipedia

   en.wikipedia.org/wiki/List_of_Runge–Kutta_methods

   Runge–Kutta methods are methods for the numerical solution of the ordinary differential equation. Explicit Runge–Kutta methods take the form. Stages for implicit methods of s stages take the more general form, with the solution to be found over all s. Each method listed on this page is defined by its Butcher tableau, which puts the ...

5. Simpson's rule - Wikipedia

   en.wikipedia.org/wiki/Simpson's_rule

   Composite Simpson's 3/8 rule is even less accurate. Integration by Simpson's 1/3 rule can be represented as a weighted average with 2/3 of the value coming from integration by the trapezoidal rule with step h and 1/3 of the value coming from integration by the rectangle rule with step 2h. The accuracy is governed by the second (2h step) term.

6. Finite difference coefficient - Wikipedia

   en.wikipedia.org/wiki/Finite_difference_coefficient

   Arbitrary stencil points. For arbitrary stencil points and any derivative of order up to one less than the number of stencil points, the finite difference coefficients can be obtained by solving the linear equations [6] where is the Kronecker delta, equal to one if , and zero otherwise. Example, for , order of differentiation :

7. Golden ratio - Wikipedia

   en.wikipedia.org/wiki/Golden_ratio

   The golden ratio is also an algebraic number and even an algebraic integer. It has minimal polynomial. This quadratic polynomial has two roots, and. The golden ratio is also closely related to the polynomial. which has roots and As the root of a quadratic polynomial, the golden ratio is a constructible number.
