. thework of integral calculus is to study changing motion in a finite space. It ismy opinion that it is hardly necessary to show further the uses of differen-tial calculus and analysis of the infinite,. the founda-tions of differential calculus, I have presented the method for differentiatingevery kind of function, for finding not only differentials of the first order,but also those of higher. theory of differential calculus, while the second part is concerned withapplications of differential calculus. The first part consists of the first ninechapters, with chapters ten through twenty-seven...
