When discussing mathematical problems, in expressions or equations related to specific variables (or unknown functions) and their derivatives, known functions or constants multiplied by unknowns are called coefficients. The term coefficient is also widely used in physics, engineering and computer technology. Such as the ratio of the partial value of a quantity to the total value, or some related figures in the relationship between the change of one quantity and the change of other quantities, are called coefficients. At this time, the coefficient is often preceded by the proper names of related phenomena or things, such as "expansion coefficient" and "carbolic acid coefficient". The numerical factor in the monomial is also called the coefficient of the monomial. The factor of the highest term in a polynomial is called the coefficient of the polynomial. Formula coefficient

14m 14

123x 123

(For example, the coefficient of 14m is 14. The coefficient of 123x is 123. ) The numerical factor in a monomial is called its coefficient. The sum of the exponents of all the letters in a monomial is called its degree. For example, the coefficient of abc is 1 and the degree is 3. The functional relationship y=x+6 has the same coefficient as the first term in y=x, which is 65440. Usually, the coefficient is not 0. The term with letters in the polynomial is called the coefficient of the term, and the term without every word is called the constant term. For example, in the polynomial: 4ab-5c+6d -7,4,-5,6 are the coefficients of terms ab, C and D containing letters, while-7 does not contain letters, so it is called a constant term. Note: If there is no numerical coefficient in the formula, it defaults to 1 time, which refers to the number except letters in a single item.
