Understanding Piecewise Smooth Curves

This video tutorial explains how to determine a piecewise smooth curve for a given curve composed of three segments, C1, C2, and C3. It focuses on deriving the equations of the lines containing these segments, forming parametric equations, and expressing the curves as vector-valued functions. The tutorial highlights the importance of understanding slopes, y-intercepts, and the use of point-slope form to find line equations. It also demonstrates how to create parametric equations and vector-valued functions to represent the curve segments accurately.
