MATLAB sections meet on Thursdays in CLICS Northwest at the same time as Tuesday recitation sections.
This course is an introduction to ordinary differential equations (ODEs). Differential equations most often arise as mathematical models of real situations, which is why scientists and engineers, as well as mathematicians, study them. In this course we will learn how to solve first and second order linear ODEs, by multiple methods, and also learn how to solve systems of first order linear ODEs.
The prerequisite for this course is a thorough knowledge of calculus. The textbook is W. E. Boyce and R. C. DiPrima, Elementary Differential Equations, 8th ed., (Hoboken, NJ: John Wiley & Sons, Inc. 2005). We will cover chapters 1, 2, 3, 5, 6 and 7.
There will be weekly homework and MATLAB assignments, due in sections (or in the AP&M sixth floor drop box for this course before midnight) on Tuesdays. Students are allowed to discuss the homework assignments among themselves, but are expected to turn in their own work — copying someone else's is not acceptable. Homework scores will contribute 10% to the final grade; MATLAB assignment scores will also contribute 10% to the final grade.
There will be two midterms, in the fourth and eighth weeks of the quarter. The final is scheduled for 11:30am Monday 11 June. Scores on the two midterms and final will contribute 22.5%, 22.5% and 35% to the final grade, respectively. There will be no makeup tests.
