We next give the example of differential operators with constant coefficients.

When the A are numbers, the equation is said to have constant coefficients.

Similarly, the model assumes a constant coefficient for population.

It consists of all those polynomials whose constant coefficient is even.

Ignore the constant coefficients, and focus attention on the form.

Therefore, a constant coefficient of viscosity cannot be defined.

Also, even with constant coefficients, it can approximately treat separation from smooth surfaces.

However, by using the orthogonal set of basis functions, it is not necessary to recalculate the constant coefficients.

The first of these has constant coefficients and is easily solved.

This is especially useful in considering ordinary linear differential equations with constant coefficients.
