That he made little use of Euler 's work is supported by the rather surprising fact that throughout his book Cramer makes essentially no use of the infinitesimal calculus in either Leibniz ' or Newton 's form, although he deals with such topics as tangents, maxima and minima, and curvature, and cites Maclaurin and Taylor in footnotes.
Na siya ginawa maliit na paggamit ng Euler 's trabaho ay suportado ng mga kamangha-mangha katunayan sa halip na sa kabuuan ng kanyang libro Cramer gumagawa ng mahalagang hindi gumamit ng katiting na katiting calculus sa alinman sa Leibniz' o Newton 's form, kahit na siya usapan na may tulad na mga paksa tulad ng tangents, maxima at minima, at kurbada, at cites Maclaurin at Taylor sa footnotes.
