Examples

In the above examples, each piecewise polynomial is defined on an interval with the same length and thus forms a uniform basis.

The idea was to start a pendulum from several different heights in order to cover a range of velocities and then to use simultaneous algebraic equations to fit a two or three term polynomial to two or three lostarc datapoints, changing the exponents until the polynomial achieved good agreement with the other lostarc data points.

This isn't a trivial difference; a model that can solve a problem in polynomial time really is fundamentally more powerful than one that takes exponential time.

And there are tons of computational complexity classes above the standard P and NP that represent problems that deterministic and nondeterministic Turing Machines can solve in polynomial time.

In this equation, d is called the polynomial's degree.

Also, all such calculations are done modulo another polynomial, which is called the irreducible polynomial for the field.

We call a polynomial p (x) with integer coefficients irreducible if p (x) cannot be written as a product of two polynomials with integer coefficients neither of which is a constant.

The degree of the polynomial is the degree of the term with highest degree.

(Since any polynomial which is zero in a neighborhood of a point must be identically zero.)
