Laurent series

We derive the Laurent series for functions that are non analytic at a point z_0 by utilizing the same technique as Taylor series, where we use the Cauchy integral formula. Because there is a point of non-analyticity, the contours form a multiply connected domain that yields additional terms beyond that of a standard Taylor series.

at 9:00 shouldnt it be R1 < |z - z0| < R2

Hard to find good videos on this subject so cudos! I do however agree that the writing is terrible and should be adjusted in future videos. Get a better board or just film a paper instead. Thumbs up otherwise.
