Description

Abstract We present a procedure and a MATHEMATICA code for the conversion of formulae expressed in terms of the trigonometric functions sin (ω x), cos (ω x) or hyperbolic functions sinh (λ x), cosh (λ x) to forms expressed in terms of η_m(Z) functions. The possibility of such a conversion is important in the evaluation of the coefficients of the approximation rules derived in the frame of the exponential fitting. The converted expressions allow, among others, a full elimination of the 0/0 undetermin...
