COEFFICIENT, n. 1. That which unites in action with something else to produce the same effect. 2. In algebra, a number or known quantity put before letters, or quantities, known or unknown, and into which it is supposed to be multiplied; as in 3x and ax, 3 and a are the coefficients of x. 3. In fluxions, the coefficient of any generating term is the quantity which arises from the division of that term by the generated quantity.

nounEtymology: New Latin coefficient-, coefficiens, from Latin co- + efficient-, efficiens efficient Date: circa 1715 1. any of the factors of a product considered in relation to a specific factor; especially a constant factor of a term as distinguished from a variable 2.a. a number that serves as a measure of some property or characteristic (as of a substance, device, or process) <coefficient of expansion of a metal> b.measure

n. 1 Math. a quantity placed before and multiplying an algebraic expression (e.g. 4 in 4x(y)). 2 Physics a multiplier or factor that measures some property (coefficient of expansion). Etymology: mod.L coefficiens (as CO-, EFFICIENT)

Coefficient Co`ef*fi"cient, n. 1. That which unites in action with something else to produce the same effect. 2. [Cf. F. coefficient.] (Math.) A number or letter put before a letter or quantity, known or unknown, to show how many times the latter is to be taken; as, 6x; bx; here 6 and b are coefficients of x. 3. (Physics) A number, commonly used in computation as a factor, expressing the amount of some change or effect under certain fixed conditions as to temperature, length, volume, etc.; as, the coefficient of expansion; the coefficient of friction. Arbitrary coefficient (Math.), a literal coefficient placed arbitrarily in an algebraic expression, the value of the coefficient being afterwards determined by the conditions of the problem.

(coefficients) A coefficient is a number that expresses a measurement of a particular quality of a substance or object under specified conditions. (TECHNICAL) ...production coefficients...N-COUNT: usu with supp
