Texas Instruments: Numb3 Rs: Trawling for an Intersection

Based off of the hit television show NUMB3RS, this lesson is designed to draw a connection between polar and parametric equations, as well as to expose students to the Trawler Problem (involving a fast boat chasing a slower boat which enters a fog bank). Students end up examining a logarithmic spiral to find the intersection of the two boats. This lesson is a good extension to the NUMB3RS lesson entitled "Spiraling Out."
