    Affine transformation (Euclidean geometry) Bäcklund transform; Bilinear transform; Box–Muller transform; Burrows–Wheeler transform (data compression) Chirplet transform; Distance transform; Fractal transform; Gelfand transform; Hadamard transform; Hough transform (digital image processing) Inverse scattering transform; Legendre ...

  3. Affine transformation - Wikipedia

    en.wikipedia.org/wiki/Affine_transformation

    Let X be an affine space over a field k, and V be its associated vector space. An affine transformation is a bijection f from X onto itself that is an affine map; this means that a linear map g from V to V is well defined by the equation () = (); here, as usual, the subtraction of two points denotes the free vector from the second point to the first one, and "well-defined" means that ...

    Note: solving for ′ returns the resultant angle in the first quadrant (< <). To find , one must refer to the original Cartesian coordinate, determine the quadrant in which lies (for example, (3,−3) [Cartesian] lies in QIV), then use the following to solve for :

  5. Canonical transformation - Wikipedia

    en.wikipedia.org/wiki/Canonical_transformation

    Restricted canonical transformations are coordinate transformations where transformed coordinates Q and P do not have explicit time dependence, i.e., = (,) and = (,).The functional form of Hamilton's equations is ˙ =, ˙ = In general, a transformation (q, p) → (Q, P) does not preserve the form of Hamilton's equations but in the absence of time dependence in transformation, some ...

  6. AP World History: Modern - Wikipedia

    The exam features a new section (Section I Part B) that requires three short answer questions, one of which is selected from two options. Each question has three parts, making for a total of 9 parts within the SAQ section. Students have forty minutes to answer these questions, and they count for twenty percent of the exam score.

  7. Transformation geometry - Wikipedia

    en.wikipedia.org/wiki/Transformation_geometry

    One author expressed the importance of group theory to transformation geometry as follows: I have gone to some trouble to develop from first principles all the group theory that I need, with the intention that my book can serve as a first introduction to transformation groups, and the notions of abstract group theory if you have never seen ...

  8. Screw theory - Wikipedia

    en.wikipedia.org/wiki/Screw_theory

    In planar transformations a translation is obtained by reflection in parallel lines, and rotation is obtained by reflection in a pair of intersecting lines. To produce a screw transformation from similar concepts one must use planes in space : the parallel planes must be perpendicular to the screw axis , which is the line of intersection of the ...

  9. Linear fractional transformation - Wikipedia

    en.wikipedia.org/wiki/Linear_fractional...

    An example of such linear fractional transformation is the Cayley transform, which was originally defined on the 3 × 3 real matrix ring. Linear fractional transformations are widely used in various areas of mathematics and its applications to engineering, such as classical geometry , number theory (they are used, for example, in Wiles's proof ...
