This is the third course of the basic sequence Calculus I, II and III, serving as the foundation of advanced subjects in all areas of mathematics. This course is designed to develop the topics of multivariate calculus. Emphasis is placed on multivariate functions, partial derivatives and multiple integrals.


Pre Requisits

Calculus-I, Calculus-II

Learning Outcomes

Upon completion of the course Calculus III, the students will be able to interpret the area enclosed between curves as a definite integral and compute its value. Set up the Riemann sum representing the volume enclosed by a geometric solid, convert the result to definite integral and compute its value. Interpret a volume of revolution of a functions graph around a given axis as a (Riemann) sum of disks or cylinder shells, convert to definite integral form and compute its value.
