What's different about the b&w versions?

Printers do a fine job of printing b&w versions of color pages, though we are all familiar with the way certain detail is lost. In particular, pure blue, red and green portions of a picture are rendered in the same shade of gray. As the default pen colors of graphs in APEX Calculus are pure blue and red, each will be printed as the same shade of gray, making it difficult to distinguish which curve in a graph is which. 

So when I created the graphics for the text, I produced two copies of each picture. One had a "color" color scheme, and the other had a "b&w" color scheme. The result is that the "b&w" figures look better printed on a grayscale printer than the color figures do.

Further, Definitions, Theorems and Key Ideas are printed in colored boxes in the color version to make them stand out on the page. This color turns to a blotchy shade of gray when printed on a grayscale printer. So in the b&w versions of the text, these boxes are only outlined in black
