Radius of Curvature Proof

The video tutorial explains how to find the radius of a circle that best approximates a curve at any point. It begins with the equation of a circle and uses calculus to differentiate and solve for variables. The tutorial derives an expression for the radius in terms of derivatives and applies it to approximate curves, ensuring the circle shares the same slope and curvature at a point. The video also discusses the use of absolute values to ensure a positive radius.

What is the relationship between the slope and curvature of the curve and the circle at a given point?
