Advent Wreath Candles. Set on the branches of the wreath are four candles: three purple candles and one pink candle. In the center of the wreath sits a white candle. As a whole, these candles represent the coming of the light of Christ into the world. On the first Sunday of Advent, the first purple candle is lit.
In mathematics,  a coefficient is a multiplicative factor in some term of a polynomial, a series or any expression; it is usually a number, but may be any expression. In the latter case, the variables appearing in the coefficients are often called parameters, and must be clearly distinguished from the other variables.
Asker's rating. Report Abuse. A constant is simply a fixed or given number (or name or symbol that stands for a fixed number) -- not a variable. A coefficient is a constant, and is a multiplier of something -- typically a variable, but also functions and other things.Example (nonsensical expression): y = 2sin(3x) +4pi 2, 3, 4, and pi are constants (and some would say 2pi is a constant). 2 and 3 are coefficients.sker's rating.
