Finding Intersection Points with Parametric Equations

This video tutorial explains how to find the point of intersection between a line and a plane using parametric equations. It begins with an introduction to the concept, followed by a detailed walkthrough of solving a problem to find the intersection point. The video then presents a second problem with a different line and plane, demonstrating how to set up and solve it. The tutorial concludes with a summary and a call to action for viewers to subscribe to the channel.

What is the main goal when finding the intersection between a line and a plane?
