Curvature, Normal Vectors, & Circle of Curvature
Correction at 22:41: The denominators in the derivative should have a exponent of 3 instead of 3/2 In this video, we talk about the curvature, or bending/turning, of a curve. We use the unit tangent vector in our calculation for curvature. We also find the principal unit normal vector to a curve as well as the circle of curvature at a point.
