About the Cover Reaching a dizzying height of 420 feet and a top speed of 120 miles per hour, the Top Thrill Dragster in Sandusky, Ohio, is the tallest and fastest roller coaster in the world. Riders of the Top Thrill Dragster accelerate to top speed in approximately four seconds and then zoom straight up on a track that rotates 90 degrees. In Chapter 4, you will learn about rates of change like speeds. About the Graphics Twisted torus. Created with Mathematica. A torus with rose-shaped cross section is constructed. Then the cross section is rotated around its center as it moves along a circle to form a twisted torus. For more information, and for programs to construct such graphics, see: www.wolfram.com
