Course introduce:

Calculus is a classical course of mathematics. It’s not only used to research the continuous models of objective world, but also as an essential foundation for the college students to learn other subjects. Calculus is a powerful tool of mathematics and are used to solve problems in practical fields. Through this course of study, students will train the ability to analyze a new situation or problem into its basic parts, and utilizing perservance, originality, abstract thinking, spatial imagination and logical reasoning in solving the problem.

Assessment of the course:

Final score=examination score*80%+(score of homework and check on work)*20%;
