With the international development of universities and the open running strategies,many universities and majors require higher-level education on teaching. Bilingualteaching and full English teaching have become widespread educational modes. Manyforeign original Calculus textbooks have been introduced in recent years, but comparedto domestic Calculus textbooks, there exist a number of differences in system, contentand styles. For example, domestic textbooks focus on profound concepts and theoreticalderivation, while foreign original textbooks emphasize the application and numericalmethods, leading to the inconvenience for readers to learn. Thus, with extensive anddeep investigation, we organized a team of teachers who have overseas study experienceand long-term teaching experience to compile this Calculus textbook, which absorbs theadvantages of both domestic and foreign textbooks, mainly reflected in the followingaspects.
1. The introduction of mathematical concepts is focused on understanding, withexplicit language and detailed depiction. Most examples contain a geometric picture toaid understanding.
2. We try to retain the rigorous derivation as domestic calculus textbooks, andmost theorems are proved.
3. The application is emphasized, embodied from examples and exercises. Wesuggest students do the exercises as much as possible to hone the ability of applyingmathematics.
