Curvature is why roller coasters use clothoid loops (not circular) – to avoid abrupt changes in ( \kappa ), which cause whiplash. The book’s exercises on radius of curvature in parametric and polar forms prepare you for real differential geometry.

Show that the evolute of an ellipse is not an ellipse but a stretched, curved shape with four cusps (an astroid again!). Then find the involute of that evolute – you return to the original ellipse, but possibly shifted. differential calculus ghosh maity part 2 pdf
