Aim :
To introduce calculus of functions of several variables, vector-valued functions and complex line integrals, and the use of integral theorems in any orthogonal curvilinear coordinates to solve calculus-related problems.
Intended Learning Outcomes:
On successful completion of the course, the students should be able to;
- Sketch level curves and level surfaces of functions of two and three variables, and sketch their surfaces and solids, and then compute their Taylor series expansions and their maximums and minimums.
- Compute double and triple integrals of scalar functions over any given 2D and 3D regions.
- Compute gradient, divergence and curl of given functions, and Laplace operator using orthogonal curvilinear coordinates and to evaluate line integrals of vector valued functions and complex valued functions.
- Evaluate surface and volume integrals of continuous vector fields over a given domain and apply integral theorems in terms of orthogonal curvilinear coordinates.
