Circle of curvature
Franke, Herbert W.
Circle, curvature, tangent to the curveThe circle of curvature is a visual expression of the curvature of a curve at a given point. The circle of curvature, or osculating circle, of a curve at a point is the circle tangent to the curve with the same curvature. This Demonstration shows the circles of curvature along several curves. For a nice animation, run the two sliders simultaneously in the back and forth modeComponente Curricular::Educação Superior::Ciências Exatas e da Terra::Matemática
