Twenty percent of America’s 14 million high school students take a trigonometry course before graduating, and many more students study trig in college. This hands-on guide helps these students get up to speed on sines, cosines, tangents, and other trig concepts using lots of example problems, all of which have fully explained solutions. In addition to the problems, the book includes a pre-test to help students gauge their overall trig knowledge, overviews of key trig concepts, and a final full-length exam covering all the topics in the book.
