Parametric Trajectories and Integrals

This lecture covers parametric trajectories in the plane, where particles A and B follow different paths parametrized by functions. It discusses the concept of tangential points, stationarity, and the comparison of trajectories. The lecture also delves into the integral calculation method of Archimedes and the concept of filling areas under curves with triangles. It concludes with the definition of integrals for continuous functions and the partition of intervals for integral calculation.
