  2. Newton's method - Wikipedia

    en.wikipedia.org/wiki/Newton's_method

    An illustration of Newton's method. In numerical analysis, the Newton–Raphson method, also known simply as Newton's method, named after Isaac Newton and Joseph Raphson, is a root-finding algorithm which produces successively better approximations to the roots (or zeroes) of a real-valued function.

    A Texas Instruments TI-84 Plus calculator display showing the Avogadro constant to three significant figures in E notation. The first pocket calculators supporting scientific notation appeared in 1972. [14] To enter numbers in scientific notation calculators include a button labeled "EXP" or "×10 x", among other variants.

    More generally, suppose that a ≥ 3 and that ω a = exp ⁠ 2πi / a ⁠ denotes the a th primitive root of unity. Then, as an application of the discrete Fourier transform , we have the formula [ 15 ] ∑ n = 0 ∞ f a n + b z a n + b = 1 a ∑ m = 0 a − 1 ω a − m b F ( ω a m z ) . {\displaystyle \sum _{n=0}^{\infty }f_{an+b}z^{an+b ...

    It was a Turing complete, general-purpose computer that used 17,468 vacuum tubes to create the circuits. At its core, it was a series of Pascalines wired together. [18] Its 40 units weighed 30 tons, occupied 1,800 square feet (167 m 2), and consumed $650 per hour (in 1940s currency) in electricity when idle. [18] It had 20 base-10 accumulators.

  9. Jacobian matrix and determinant - Wikipedia

    en.wikipedia.org/wiki/Jacobian_matrix_and...

    The Jacobian at a point gives the best linear approximation of the distorted parallelogram near that point (right, in translucent white), and the Jacobian determinant gives the ratio of the area of the approximating parallelogram to that of the original square. If m = n, then f is a function from R n to itself and the Jacobian matrix is a ...
