Coordinate Geometry: Section Formula and Midpoint Formula

The video tutorial focuses on the section formula in coordinate geometry. It begins with an example using two towns, A and B, to explain how to find a point P that divides the line segment in a given ratio. The tutorial introduces a mathematical trick to simplify finding coordinates for any ratio, leading to the derivation of the section formula. Additionally, the midpoint formula is derived as a special case of the section formula. The session concludes with a recap of the key concepts covered.
