About the Cover

The sailboard was invented by Newman Drake in the 1950s, and the
sport was popularized by Californians Jim Drake and Hoyle Schweitzer
in the 1970s. The sport spread rapidly from California, throughout the
United States and around the world. By standing on the rudderless
board and maneuvering the sail to glide along the water’s surface,
a sailboarder can reach speeds of up to 45 miles per hour.
In Chapter 4, you will learn to solve problems involving rate,
speed, and distance.

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/r/textbook.
