Curves in Space: Singularities and Developments

This lecture explores the concept of curves in space, focusing on singularities and developments. It covers topics such as the rotation of the osculating circle, the Frenet frame, and extrinsic and intrinsic singularities. The instructor discusses the relationship between the osculating circle and the Frenet frame, as well as the properties of maximums and minimums on curves. The lecture also delves into the development curve and the developing curve, illustrating how they are related. Various exercises and examples are provided to deepen the understanding of these geometric concepts.
