Course outcome:

On completion of this course, students are able to

  • Use partial derivatives to calculate rates of change of multivariate functions.
  • Analyze position, velocity, and acceleration in two or three dimensions using the calculus of vector valued functions.
  • Recognize and solve first-order ordinary differential equations, Newton’s law of cooling
  • Use matrices techniques for solving systems of linear equations in the different areas of Linear Algebra.

Question paper pattern:


  • Each full Question consisting of 16 marks
  • There will be 2 full questions(with a maximum of four sub questions) from each module.
  • Each full question will have sub questions covering all the topics under a module.
  • The students will have to answer 5 full questions, selecting one full question from each module.
