Course outline

Instructor: Dr. Gantumur Tsogtgerel

Prerequisite: MATH 325 (Honours ODE) or MATH 315 (ODE), COMP 202 or permission of instructor.

Corequisite: MATH 255 (Honours Analysis 2) or MATH 243 (Analysis 2).

Restriction: Intended primarily for Honours students.

Calendar description: Error analysis. Numerical solutions of equations by iteration. Interpolation. Numerical differentiation and integration. Introduction to numerical solutions of differential equations.

Topics to be covered:

Homework: We will have 3–4 homework assignments. Each assignments will consist of theoretical and programming components.

Exams: A midterm exam and a final exam. Each exam will consist of a theory exam in class, and a programming ("lab") exam to be done at home.

Grading: Homework 30%, Midterm 20%, Final 50%.

Midterm exam

The following topics will be covered.

Final exam

The final course grade will be computed as Homework 30% + MAX{ Final 70% , Final 50% + Midterm 20% }
