Dr. Neil Balmforth


This course provides an introduction to solution methods for ODEs.

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''
