Pilot's Flight Path Calculations

The video tutorial explains how to solve an application problem using the Law of Cosines. A pilot flies in two directions, making a course correction, and the task is to find the distance from the starting point. The problem is set up as a triangle, and distances are calculated based on speed and time. The angle is determined using the course correction, and the Law of Cosines is applied to find the unknown side. The final calculation reveals the distance traveled by the plane.
