In this video, we break down a common Leaving Cert Higher Level coordinate geometry problem involving circles and a real-world submarine scenario. We walk through the step-by-step process of finding the equation of a circle using the center and radius, and then show you how to verify if a specific point lies on that circle. This is a must-watch for anyone preparing for Paper 2!
Key Concepts Covered:
Finding the equation of a circle using the formula (x-h)^2 + (y-k)^2 = r^2.
Identifying the center (h, k) and radius from a coordinate diagram.
Verifying point coordinates by substituting them into a circle's equation.
Interpreting coordinate geometry word problems.
