    en.wikipedia.org/wiki/Help:Advanced_table_formatting

    There are several advanced table formatting techniques to improve the display or editing of wikitables in Wikipedia. Most of the tips involve use of standard text-editors. While some special software packages exist, to allow customized editing, they are typically not available when travelling to other computers for wiki-editin

  3. Modulo - Wikipedia

    en.wikipedia.org/wiki/Modulo

    In computing, the modulo operation returns the remainder or signed remainder of a division, after one number is divided by another, called the modulus of the operation.. Given two positive numbers a and n, a modulo n (often abbreviated as a mod n) is the remainder of the Euclidean division of a by n, where a is the dividend and n is the divisor.

    Besides differences in the schema, there are several other differences between the earlier Office XML schema formats and Office Open XML. Whereas the data in Office Open XML documents is stored in multiple parts and compressed in a ZIP file conforming to the Open Packaging Conventions, Microsoft Office XML formats are stored as plain single monolithic XML files (making them quite large ...

  5. Dimensional analysis - Wikipedia

    derivative of position with respect to time (dx/dt, velocity) has dimension T −1 L—length from position, time due to the gradient; the second derivative (d 2 x/dt 2 = d(dx/dt) / dt, acceleration) has dimension T −2 L. Likewise, taking an integral adds the dimension of the variable one is integrating with respect to, but in the numerator.

  6. Fourier series - Wikipedia

    en.wikipedia.org/wiki/Fourier_series

    In the latter case, the exponential form of Fourier series synthesizes a discrete-time Fourier transform where variable represents frequency instead of time. In general, the coefficients are determined by analysis of a given function s ( x ) {\displaystyle s(x)} whose domain of definition is an interval of length P {\displaystyle P} .

  7. Quaternion - Wikipedia

    This eliminates the need to change representations and to encode new data structures and methods, which is traditionally required when augmenting linear algebra with quaternions. Rotors are universally applicable to any element of the algebra, not just vectors and other quaternions, but also lines, planes, circles, spheres, rays, and so on.

    The outside of the cambium produces new phloem cells, which do "food" transport. The inside of the cambium produces new xylem cells, which do water & nutrient transport from the roots. Old phloem gets shed with the bark, but old xylem just sticks around, forming a core made of dead cells that provides structural support to the tree.
