If that specific function turns out not to be good enough, a different function needs to be tried. We propose here a different approach which is to use instead the function g<sub>s</sub>(V), where g<sub>s</sub> is the adiabatic gamma along the principal isentrope, as defined by Eq. (2) below. By choosing g<sub>s</sub> we don’t have to assume the form of the function from the outset. Instead, we define the function by a set of points (n≥4), and we’re able to define the amplitudes of these points recursively. In what follows we first write down the equations for determining the values of g<sub>si</sub> for the specific volumes V<sub>i</sub>, and then work out an example with n=4. We show that even for n=4 the reproduction of test data is quite good, and also that the results are not sensitive to the exact choice of the values of V<sub>i</sub>.</p>}, number={1}, journal={European Journal of Applied Sciences}, author={Partom, Yehuda}, year={2023}, month={Feb.}, pages={519–526} }
