  2. Screw theory - Wikipedia

    en.wikipedia.org/wiki/Screw_theory

    Important theorems of screw theory include: the transfer principle proves that geometric calculations for points using vectors have parallel geometric calculations for lines obtained by replacing vectors with screws; [1] Chasles' theorem proves that any change between two rigid object poses can be performed by a single screw; Poinsot's theorem ...

    en.wikipedia.org/wiki/Miquel's_theorem

    The Pivot Theorem for various triangles Miquel's theorem is a result in geometry , named after Auguste Miquel , [ 1 ] concerning the intersection of three circles, each drawn through one vertex of a triangle and two points on its adjacent sides.

    Next, the pivot row must be selected so that all the other basic variables remain positive. A calculation shows that this occurs when the resulting value of the entering variable is at a minimum. In other words, if the pivot column is c, then the pivot row r is chosen so that / is the minimum over all r so that a rc > 0

  5. Gaussian elimination - Wikipedia

    en.wikipedia.org/wiki/Gaussian_elimination

    Animation of Gaussian elimination. Red row eliminates the following rows, green rows change their order. In mathematics, Gaussian elimination, also known as row reduction, is an algorithm for solving systems of linear equations. It consists of a sequence of row-wise operations performed on the corresponding matrix of coefficients.

  6. Pivot element - Wikipedia

    en.wikipedia.org/wiki/Pivot_element

    A pivot position in a matrix, A, is a position in the matrix that corresponds to a row–leading 1 in the reduced row echelon form of A. Since the reduced row echelon form of A is unique, the pivot positions are uniquely determined and do not depend on whether or not row interchanges are performed in the reduction process.

    Geometry Dash is a 2013 side-scrolling music platforming game series created by Swedish game developer Robert Topala. It was released on 13 August 2013 for iOS and Android , with versions for Windows and macOS following on 22 December 2014.

  8. Shear mapping - Wikipedia

    en.wikipedia.org/wiki/Shear_mapping

    In plane geometry, a shear mapping is an affine transformation that displaces each point in a fixed direction by an amount proportional to its signed distance from a given line parallel to that direction. [1] This type of mapping is also called shear transformation, transvection, or just shearing.

  9. Geometric Exercises in Paper Folding - Wikipedia

    A discussion of the symmetries of the plane includes congruence, similarity, [7] and collineations of the projective plane; this part of the book also covers some of the major theorems of projective geometry including Desargues's theorem, Pascal's theorem, and Poncelet's closure theorem. [6]
