A geometric introduction to complex variables, complex integration, and Laplace transforms. Materials below include lecture notes and resources from previous semesters.

Course outline

Before the midterm

  • The relationship between the vector spaces $\mathbb{R}^2$ and $\mathbb{C}$, and what makes the complex plane different
  • Complex variables and functions
  • Limits and continuity
  • Complex differentiability, harmonic functions, and analytic functions

After the midterm

  • Line integrals and complex integration
  • Laplace transforms
