  We review a method providing explicit formulas for the Jack polynomials. Our
method is based on the relation of the Jack polynomials to the eigenfunctions
of a well-known exactly solvable quantum many-body system of
Calogero-Sutherland type. We also sketch a generalization of our method
allowing to find the exact solution of the elliptic generalization of the
Calogero-Sutherland model. We present the resulting explicit formulas for
certain symmetric functions generalizing the Jack polynomials to the elliptic
case.
