{ "item_title" : "Advanced Trigonometry", "item_author" : [" Art Cockerham "], "item_description" : "This book is the first of a series covering the math concepts tested on the ACT. Our first volume focuses on Advanced Trigonometry. You'll find explanations of the topics, example problems and fully done-out solutions. In the second half of the book, there are a number of problems that you can work out on your own. These, too, have fully worked-out solutions so you can check your work and really understand how to apply what you've learned to those tough problems that appear at the end of the ACT Math section. The topics addressed in this book include the Law of Cosines and the Law of Sines, advanced topics in right triangle trigonometry, the three reciprocal trig functions (secant, cosecant and cotangent) and properties of functions. Students who are taking the ACT before finishing Pre-Calculus will find this volume particularly helpful. It will cover those topics you might not have gotten to in school yet. (But even if you've made it through Pre-Calculus, a little extra practice never hurts, right? ?)", "item_img_path" : "https://covers4.booksamillion.com/covers/bam/1/50/777/121/1507771215_b.jpg", "price_data" : { "retail_price" : "7.95", "online_price" : "7.95", "our_price" : "7.95", "club_price" : "7.95", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
