Everything about Coefficient
Multiplicative factor in a mathematical expression
In mathematics, a coefficient is a multiplicative factor involved in some term of a polynomial, a series, or any other type of expression. It may be a number without units, in which case it is known as a numerical factor. It may also be a constant with units of measurement, in which it is known as a constant multiplier. In general, coefficients may be any expression. When the combination of variables and constants is not necessarily involved in a product, it may be called a parameter. For example, the polynomial has coefficients 2, −1, and 3, and the powers of the variable in the polynomial have coefficient parameters, , and. Wikipedia →
