In mathematics, a monomial is, roughly speaking, a polynomial which has only one term. Two definitions of a monomial may be encountered: A monomial, also called a power product or primitive monomial, [1] is a product of powers of variables with nonnegative integer exponents, or, in other words, a product of variables, possibly with repetitions. [2]
Degree: The maximum exponents among the monomials. Factor: An expression being multiplied. Linear factor: A factor of degree one. Coefficient: An expression multiplying one of the monomials of the polynomial. Root (or zero) of a polynomial: Given a polynomial p(x), the x values that satisfy p(x) = 0 are called roots (or zeroes) of the polynomial p.
Every irrational fraction in which the radicals are monomials may be rationalized by finding the least common multiple of the indices of the roots, and substituting the variable for another variable with the least common multiple as exponent. In the example given, the least common multiple is 6, hence we can substitute = to obtain
It follows that this greatest common divisor is a non constant factor of (). Euclidean algorithm for polynomials allows computing this greatest common factor. For example, [ 10 ] if one know or guess that: P ( x ) = x 3 − 5 x 2 − 16 x + 80 {\displaystyle P(x)=x^{3}-5x^{2}-16x+80} has two roots that sum to zero, one may apply Euclidean ...
In other words, a real image is an image which is located in the plane of convergence for the light rays that originate from a given object. Examples of real images include the image produced on a detector in the rear of a camera, and the image produced on an eyeball retina (the camera and eye focus light through an internal convex lens).
If two or more factors of a polynomial are identical, then the polynomial is a multiple of the square of this factor. The multiple factor is also a factor of the polynomial's derivative (with respect to any of the variables, if several). For univariate polynomials, multiple factors are equivalent to multiple roots (over a suitable extension field).
Thus the canonical images of the reduced words in / form a -spanning set. [1] The idea of non-commutative Gröbner bases is to find a set of generators g σ {\displaystyle g_{\sigma }} of the ideal I {\displaystyle I} such that the images of the corresponding reduced words in k X / I {\displaystyle k\langle X\rangle /I} are a k {\displaystyle k ...
A given monomial's presence or absence in a polynomial corresponds to that monomial's coefficient being 1 or 0 respectively. The Zhegalkin monomials, being linearly independent, span a 2 n-dimensional vector space over the Galois field GF(2) (NB: not GF(2 n), whose multiplication is quite different).
