Lecture 2: Tangential & Normal Vectors

Video Description: Herb Gross explains how a vector is tangent to a curve at a point as a function of arc length. Likewise, he explains how a vector is normal to a curve as a function of the derivative of the tangent with regard to arc length and curvature. Prof. Gross presents an example tracking the velocity and acceleration of a particle moving along a curve.  Finally, he discusses similar issues and examples for 3-dimensional curves (binormal).
