Using existence theorems for the solutions to differential equations, Fatou was able to prove rigorously certain results on planetary orbits which Gauss had suggested by only verified with an intuitive argument.
Gamit ang pagkakaroon theorems para sa mga solusyon sa mga kaugalian equation, Fatou ay able sa patunayan rigorously certian resulta sa pamplaneta orbits na gauss had iminungkahing lamang sa pamamagitan ng napatunayan na may isang intuitive argument.
