GCSE Secondary Maths Age 13-17 - Graphs: Equation of a Tangent - Explained

The video tutorial covers solving a geometry problem involving a circle and a tangent line. It begins with sketching the circle and plotting a point on it. The instructor then explains how to find the equation of the tangent line at that point by calculating the gradient and intercept. The process involves understanding the relationship between the radius and the tangent, and using algebraic manipulation to derive the final equation. The tutorial emphasizes the importance of visual aids and methodical problem-solving.
