An example of coefficient is 6 in the following algebra equation, 6x - 2.
- a factor that contributes to produce a result
- Math. a number or algebraic symbol prefixed as a multiplier to a variable or unknown quantity (Ex.: x in x(y+z),6 in 6ab)
- Physics a number, constant for a given substance, used as a multiplier in measuring the change in some property of the substance under given conditions: the coefficient of expansion
Origin of coefficientco- + efficient: origin, originally an adjective meaning “cooperating”
