These cover pages are the whole story. The text itself just gives you practice in using the formulas. You can use those cover pages for many years after you finish the book. The trick is to really understand each topic as you go. At least do them up to the story problems.
Story problems are a special case.
You don't need them to learn the math technique itself. In a way, you are really learning physics, chemistry, surveying, engineering, etc. So do the story problems in each section, but don't panic if you can't see how to get a few of them turned into math. The biggest problem with calculus is that people think it is complex. So they spend a year or so on all the nuances of beginning calculus, get discouraged, and never get any further.
