Course Content

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.
