When discussing mathematical problems, in the expressions or equations related to specific variables (or unknown functions) and their derivatives, the known functions or constants multiplied by the unknowns are called coefficients. The term coefficient is also widely used in physics, engineering, computer technology and other fields, such as the ratio of the partial value of a quantity to the total value, or a quantity
