Query: Single-use Single-variable Calculus Textbook

The examples in this book are insufficient both in quantity and quality. Stewart only uses one basic example problem for most of the topics and leaves you to figure out advanced concepts by yourself.When taking Calc II, I was forced to supplement the inadequate help offered by the poor examples of this book with other textbooks and frequent Google searches. This book was definitely not worth the exorbitant amount of money for the few times that it was actually useful.
