โœฆ Synopsis


The behaviour of an algebraic and a trigonometric polynomial with real random coefficients is reviewed, and the number of times that the curves representing these polynomials cross any real line in the zy-plane is presented.

In this paper we find the expected number of zero crossings for a general algebraic polynomial, \(\sum_{j=1}^{n} a_{j}\left(\alpha x^{j}+\beta x^{-j}\right)\), and a general hyperbolic polynomial, \(\sum_{j=1}^{n} a_{j}(\alpha \cosh j x+\beta \sinh j x)\), where \(\alpha\) and \(\beta\) are constant
