Anouncements: the course webpage on CANVAS provides more information and details about this course

Some video lectures:
Lecture 1 (linear, second-order, constant-coefficient ODEs)
Lecture 2 (sample ODE problems)
Lecture 3 (mechanical oscillators)
PDE example (material at the very end of the course)

The syllabus:
I. First-order ODEs (integrating factors, separable equations)
II. Second-order, constant coefficient ODEs (real, repeated and complex roots; homogeneous and inhomogeneous)
III. Systems of ODEs
IV. Laplace Transform methods
V. Fourier series
VI. Solution of partial differential equations by separation of variables

Assessment will involve coursework (homework problems) and examination.

Recommended texts:
Boyce and DiPrima, "Elementary differential equations and boundary value problems"
E. Kreiszig, "Advanced Engineering Mathematics"
On-line "Notes on Diffy Qs" by J. Lebl

Office hours: Monday at 1pm, Tuesday at 1pm
