| Abstract: |
| Let S２(T)be the 2-subdivision of triangle domain T.When f(P)∈Ｃ1（Ｔ） is piecewisequadratic function in S２(T),we determine the deficcncy and recursive formula.of Bernsteinpolynomials of f (P).The complexities of Bernstein polynomials for piecewise quadraticfunctions in more general conditions are illustrated by some examples. |
