Bernstein polynomial (Definition)

The Bernstein polynomials of degree $ n$ are defined by

$\displaystyle B_{i}^{n}(t)={n\choose i}t^i (1-t)^{n-i} \quad\quad i=0,1,2,\dots,n$
where $ {n\choose i}$ is the binomial coefficient.

Bernstein polynomials are used extensively in interpolation theory and in computer graphics. They can be computed efficiently using the de Casteljau's algorithm.
