2BA1: the second half-year
The purpose of this course is to give an overview of some important ideas
and techniques in mathematics. We will discuss ordinary differential
equations, Fourier analysis, quaternions.
- Ordinary differential equations. Examples.
- Homogeneous equations with constant coefficients. Operator notation
and its applications.
- Inhomogeneous equations with constant coefficients.
- Numerical methods of solving ordinary differential equations.
- Integral inner product. Orthogonality of trigonometric functions.
- Fourier series. Applications of Fourier series. Euler's formula for
the sum of inverse squares.
- Discrete Fourier transform. Application to multiplication of large integers.
- Quaternions, vectors in 3-space, and rotations.
- Basics of number theory. Number theory and cryptography.
There will be two home assignments during the second half of the year.
You can find some lecture notes related to this course on the course web page
