  2. Vector algebra - Wikipedia

    en.wikipedia.org/wiki/Vector_algebra

    2. Types of Vectors • Zero Vector (\mathbf{0}): Magnitude is zero. • Unit Vector (\hat{A}): Magnitude is one. • Equal Vectors: Same magnitude and direction. • Negative Vector: Same magnitude but opposite direction. • Collinear Vectors: Parallel or anti-parallel vectors. • Coplanar Vectors: Lie in the same plane. 3. Operations on Vectors

  3. Free module - Wikipedia

    en.wikipedia.org/wiki/Free_module

    Let R be a ring. R is a free module of rank one over itself (either as a left or right module); any unit element is a basis. More generally, If R is commutative, a nonzero ideal I of R is free if and only if it is a principal ideal generated by a nonzerodivisor, with a generator being a basis. [3]

  4. Operation (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Operation_(mathematics)

    Vectors can be added and subtracted. [5] Rotations can be combined using the function composition operation, performing the first rotation and then the second. Operations on sets include the binary operations union and intersection and the unary operation of complementation. [6] [7] [8] Operations on functions include composition and ...

  5. Arithmetic - Wikipedia

    en.wikipedia.org/wiki/Arithmetic

    Vector arithmetic and matrix arithmetic describe arithmetic operations on vectors and matrices, like vector addition and matrix multiplication. [141] Arithmetic systems can be classified based on the numeral system they rely on. For instance, decimal arithmetic describes arithmetic operations in the decimal system.

  6. Congruence relation - Wikipedia

    en.wikipedia.org/wiki/Congruence_relation

    The corresponding addition and multiplication of equivalence classes is known as modular arithmetic. From the point of view of abstract algebra, congruence modulo is a congruence relation on the ring of integers, and arithmetic modulo occurs on the corresponding quotient ring.

  7. List of numerical libraries - Wikipedia

    MFEM is a free, lightweight, scalable C++ library for finite element methods. Intel MKL, Intel Math Kernel Library (in C and C++), a library of optimized math routines for science, engineering, and financial applications, written in C/C++ and Fortran. Core math functions include BLAS, LAPACK, ScaLAPACK, sparse solvers, fast Fourier transforms ...

  8. Computational complexity of mathematical operations - Wikipedia

    en.wikipedia.org/wiki/Computational_complexity...

    The elementary functions are constructed by composing arithmetic operations, the exponential function (), the natural logarithm (), trigonometric functions (,), and their inverses. The complexity of an elementary function is equivalent to that of its inverse, since all elementary functions are analytic and hence invertible by means of Newton's ...

  9. Algebra over a field - Wikipedia

    en.wikipedia.org/wiki/Algebra_over_a_field

    In mathematics, an algebra over a field (often simply called an algebra) is a vector space equipped with a bilinear product.Thus, an algebra is an algebraic structure consisting of a set together with operations of multiplication and addition and scalar multiplication by elements of a field and satisfying the axioms implied by "vector space" and "bilinear".
