Learning outcomes

The purpose of this course is to provide a complete knowledge of numerical methods for solving problems that appear in Science and Technology.

More precisely the aim of this course is the comprehension of the basic numerical methods for approximating solutions of various mathematical problems using a computer.

Emphasis is also given on the theoretical/mathematical background of these methods for their full comprehension.

After the successful completion of this course, the student should be able to:

  • understand the floating point arithmetic and floating point numbers.
  • understand, calculate and estimate the error that occurs from approximate solutions of problems.
  • approximate solutions of systems of linear and non-linear equations, using basic arithmetic methods. 
  • approximate solutions of non-linear equations, using basic arithmetic methods.
  • describe the behavior of functions in one variable using suitable interpolation polynomials. 
  • approximate the derivative and the integral functions in one variable, using arithmetic differentiation and integration methods.
  • apply basic arithmetic methods for solving simple differential equations.

Learning Activities and Teaching Methods

The course evaluation derives from:

  • 3 compulsory exercises during the semester: counting 30% in the final grade.
  • final exam: counting 70% in the final grade.

Final Grade = (0.3*M.V. Exercises) + (0.7*Final Exam)

One must have: Final Grade >= 5
