Webster's 1828 Dictionary

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.

 

COEFFICIENTLY

adv. By cooperation.

2. Etym: [Cf. F. coefficient. ] (Math. )

 

Defn: 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 )

 

Defn: 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.

 

New American Oxford Dictionary

coefficient

co ef fi cient |ˌkōəˈfiSHənt ˌkoʊəˈfɪʃənt | ▶noun 1 Mathematics a numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g., 4 in 4x y ). 2 Physics a multiplier or factor that measures some property: coefficients of elasticity | the drag coefficient. ORIGIN mid 17th cent. (in the sense ‘cooperating to produce a result ’): from modern Latin coefficient-, from com- ‘together ’ + efficient- ‘accomplishing ’ (see efficient ).

 

coefficient of friction

co ef fi cient of fric tion ▶noun the ratio between the force necessary to move one surface horizontally over another and the pressure between the two surfaces.

 

coefficient of viscosity

co ef fi cient of vis cos i ty ▶noun Physics the degree to which a fluid resists flow under an applied force, expressed as the ratio of the shearing stress to the velocity gradient. The coefficient of viscosity of liquids decreases as temperature increases because the bonds between molecules are weakened.
