  2. Polynomial - Wikipedia

    en.wikipedia.org/wiki/Polynomial

    For example, the term 2x in x 2 + 2x + 1 is a linear term in a quadratic polynomial. ... Polynomials can be classified by the number of terms with nonzero ...

  3. Multinomial theorem - Wikipedia

    en.wikipedia.org/wiki/Multinomial_theorem

    The number of terms in a multinomial sum, ... For example, the number of distinct permutations of the letters of the word MISSISSIPPI, which has 1 M, 4 Is, 4 Ss, and ...

  4. Trinomial expansion - Wikipedia

    en.wikipedia.org/wiki/Trinomial_expansion

    Layers of Pascal's pyramid derived from coefficients in an upside-down ternary plot of the terms in the expansions of the powers of a trinomial – the number of terms is clearly a triangular number. In mathematics, a trinomial expansion is the expansion of a power of a sum of three terms into monomials. The expansion is given by

  5. Term (logic) - Wikipedia

    en.wikipedia.org/wiki/Term_(logic)

    A term that doesn't contain any variables is called a ground term; a term that doesn't contain multiple occurrences of a variable is called a linear term. For example, 2+2 is a ground term and hence also a linear term, x⋅(n+1) is a linear term, n⋅(n+1) is a non-linear term. These properties are important in, for example, term rewriting.

  6. Sequence - Wikipedia

    en.wikipedia.org/wiki/Sequence

    Other examples of sequences include those made up of rational numbers, real numbers and complex numbers. The sequence (.9, .99, .999, .9999, ...), for instance, approaches the number 1. In fact, every real number can be written as the limit of a sequence of rational numbers (e.g. via its decimal expansion, also see completeness of the real ...

  7. Constant term - Wikipedia

    en.wikipedia.org/wiki/Constant_term

    For example, in the quadratic polynomial, + +, The number 3 is a constant term. [1] After like terms are combined, an algebraic expression will have at most one constant term. Thus, it is common to speak of the quadratic polynomial

  8. Maximum term method - Wikipedia

    en.wikipedia.org/wiki/Maximum_term_method

    The maximum-term method is a consequence of the large numbers encountered in statistical mechanics.It states that under appropriate conditions the logarithm of a summation is essentially equal to the logarithm of the maximum term in the summation.

  9. Empty sum - Wikipedia

    en.wikipedia.org/wiki/Empty_sum

    In mathematics, an empty sum, or nullary sum, [1] is a summation where the number of terms is zero. The natural way to extend non-empty sums [ 2 ] is to let the empty sum be the additive identity . Let a 1 {\displaystyle a_{1}} , a 2 {\displaystyle a_{2}} , a 3 {\displaystyle a_{3}} , ... be a sequence of numbers, and let
