A UNSW Sydney mathematician has discovered a new method to tackle algebra's oldest challenge—solving higher polynomial equations. Polynomials are equations involving a variable raised to powers, such ...
Jackson type theorems are obtained for monotone and comonotone approximation. Namely (i) If f(x) is a function such that the kth difference of f is $\geqq0$ on [ a, b] then the degree of approximation ...
