## Syllabus

Laplace Transform Theory
The (one-sided) Laplace transform and its existence. Use of Laplace transforms in solving simple ODEs with constant coefficients and given boundary conditions. Step functions and their transforms. Laplace transforms of standard functions. Uniqueness of the inverse. Elementary properties - linearity, first and second shifting theorems, change of scale. Transforms of derivatives and integrals and of products with powers of t. Transforms of periodic functions.The limit of F(s) as s->infinity. The initial and final value theorems and their uses. Laplace transforms of some further special functions - the saw-tooth function, the dirac delta function. Theorems relating to inversion. The solution of slightly more complicated ordinary differential equations with given initial or boundary conditions - constant coefficient equations, simultaneous equations, some equations with non-constant coefficients, equations with discontinuous forcing terms. (About 8 lectures)
Fourier series:
Definition of Fourier series. Calculation of coefficients in easy cases. Examples of whole and half range series over various ranges. Elementary properties. (About 5 lectures)
Eigenvalues, eigenvectors and eigenfunctions:
Eigenvalues and eigenvectors of matrices. Simple harmonic equation. Eigenvalues and eigenfunctions of the simple-harmonic equation with various boundary conditions. Applications of eigenvalues, eigenvectors and eigenfunctions. (About 5 lectures)
