In today's lecture: i introduced ¡­

In today's lecture: i introduced the concept of derivative of a complex function and defined analyticity. The Cauchy-Riemann equations for ensuring differentiability were also introduced.

In the next lecture: I will prove sufficient conditions for checking analyticity. Harmonic functions (solutions of the Laplace equation) will be introduced and related to analytic functions.

Next lecture in B1036, NHA.
