Mathematical analysis is awesome, a basic course for mathematics majors. We spent three semesters studying the upper and lower parts of the number textbook of Fudan University. In the video, unary, multivariate calculus and calculus focus on fractional points, which actually include limit, improper integral, series and so on. Linear algebra and differential equations are actually separate courses, called advanced algebra, ordinary differential equations, partial differential equations, numerical solutions of differential equations and so on.
