A significant reason for the widespread adoption of this series is the wealth of supplementary materials that accompany it. For students and teachers wondering what comes with the textbook, the resources are extensive.
The final chapters hinted at concepts that seemed to belong to a higher realm—rates of change, slopes of curves, and the idea of an infinite series. The textbook introduced the notion of a limit with a simple illustration: a runner approaching a finish line, never quite crossing it, but getting ever closer.
