Pre-requisites: Maths 3 1 0 4


To enhance problem solving skills of engineering students using a powerful problem solving tool namely numerical methods. The tool is capable of handling large systems of equations, nonlinearities and complicated geometries that are common in engineering practice but often impossible to solve analytically. 


On completion of this course, the students will be able to

  1. Apply various numerical methods and appreciate a trade off in using them.
  2. Understand the source of various types of errors and their effect in using these methods.
  3. To distinguish between Numerical and Analytical methods along with their Merits and demerits.
  4. Understand the use of digital computers in implementation of these methods.
  5. Develop a code in C/C++ for the solution of problems that may not be solved by analytical methods.
