WebA monomial is a one-termed polynomial. Monomials have the form f (x)=ax^n f (x) = axn where a a is a real number and n n is an integer greater than or equal to 0 0. In this investigation, we will analyze the symmetry of several monomials to see if we can come up with general conditions for a monomial to be even or odd. WebWe thereby obtain the trace formulas. trΛk(A) = ek(λ1, ⋯, λn); trSk(A) = hk(λ1, ⋯, λn), where ek is the k th elementary symmetric polynomial and hk the k th complete homogeneous symmetric polynomial.
