## Mathematics – III

### Course Objectives:

1. The course is meant to equip the scholars with the mandatory mathematical skills associated techniques that ar essential for an engineering course.

2. the abilities derived from the course can facilitate the coed from a necessary base to develop analytic and style ideas.

3. perceive the foremost basic numerical ways to resolve cooccurring linear equations.

### Course Outcomes:

**At the tip of the Course, Student are in a position to: **

1. verify rank, Manfred Eigenvalues and Eigen vectors of a given matrix and solve cooccurring linear equations.

2. Solve cooccurring linear equations numerically mistreatment numerous matrix ways.

3. verify double integral over a vicinity and triple integral over a volume.

4. Calculate gradient of a scalar perform, divergence and curl of a vector perform. verify line, surface and volume integrals. Apply inexperienced, Stokes and Gauss divergence theorems to calculate line, surface and volume integrals.
