    • n coefficient In algebra, a number or other constant placed before and multiplying an unknown quantity or variable or an expression containing such quantities; also, a number multiplying a constant or known quantity expressed algebraically—that is, by the letters a, b, etc. Thus, 3 is the coefficient of x, 2ab the coefficient of y, and 2 the coefficient of ab. in the polynomial 3x + 2aby.
    • n coefficient In physical, a numerical quantity, constant for a given substance, and used to measure some one of its properties: as, the coefficient of expansion of any substance is the amount which the unit of length (surface or volume) expands in passing from 0° to 1° C.
