Bonnet Formulas and the Second Mean Value Theorem in Studying of Socio-economic Systems

The second mean value theorem causes interest as a possible premise for a new method for finding the mean values. The purpose of this work is to indicate variants of two Bonnet formulas and the second mean value theorem in the differential calculus, applying them to studying socio-economic systems, which can be described with some particular function. These variants of the Bonnet formulas and the second mean value theorem allow calculating the parameters of mean values easier, since they enter their equations directly and linearly.
