Lecture
This lecture covers the concept of curl in 2D vector fields, explaining how it represents rotation. Through examples, the instructor demonstrates how to calculate the curl and interpret its positive and negative values. The lecture also introduces vector analysis, focusing on gradient, curl, and divergence, and their applications in physics, particularly Maxwell's equations. Additionally, the lecture delves into curve integrals, defining curves, tangential vectors, and speed along a curve, emphasizing the importance of parameterization in curve integrals.
