Application of Polynomial Approximation Method to Drop Water Evaporation

Abstract

In the paper our method for construction of orthonormal polynomials - orthonormal polynomial expansion method [OPEM] - is applied to water contact angle variations. Some special features of the method are developed for this purpose. The total variance method is demonstrated to include the errors in both dependent and independent variables. Two polynomial expansions are presented for approximating function: orthonormal and "usual" ones.
