This is a traditional course covering both trigonometry and some analytic geometry. Graphing calculators are referenced throughout the text and demonstrated throughout the video as well. Although these calculators can be somewhat expensive, they can be critical in demonstrating equations and the relationship between the algebraic form (the equation) and the geometric form (the graph). The TI-83 Plus (or TI-84 Plus) is recommended. If students are not already familiar with the calculator, they should go through the user-friendly instructions that come with it and learn the calculator techniques on a need-to-know basis as they are encountered during the course. Keep in mind that Chalk Dust provides (quality) technical support by phone or e-mail so calculator issues are not a big deal. (A complete solutions guide is part of the sixth edition Trigonometry course.) Note: Precalculus covers the content of Trigonometry and College Algebra, so students need not do either of those courses in addition to Precalculus. Trigonometry is a set of 10 videotapes that cover all of a typical high-school trig course. Assuming the classroom teacher makes it all the way through the book--most don't. The courde is subtitled "A Graphing Approach" and you can purchase an optional reference text by that name, e.g., Trigonometry: A Graphing Approach, written by Larson, Hostetler, and Edwards, and published by D.C. Heath. Your video instructor is Dana Mosely, a man with over 15 years classroom teaching experience and 8 years' experience as D.C. Heath's video instructor in mathematics. As always, he divides his time between addressing you directly and drawing on and pointing to the blackboard. When possible, grids are prepared in advance, so no time is wasted watching him set up the black board. Mr. Mosely's sine curves are just as beautiful as his straight lines--unlike other instructors, his blackboard work is a joy to watch. He also is clearly comfortable with the topic, to the point of calling sine function values "these rascals here." No stuffy, unintelligible mystique here! The tapes on this trig course are mostly longer than those in other Chalk Dust courses. Tape 1, "Prerequisites," is almost 4 hours long. It goes from a lecture on the real number system, through graphing in the Cartesian plane, to inverse functions. Tape 2 is a whopping 4 hours and 26 minutes, and covers measurements in radians and degrees, basic trig functions as they relate to unit circles/right triangles/any angle, graphing trig functions and inverse trig functions, and trig applications. The remaining videotapes cover "additional topics in trigonometry," complex numbers, exponential and logarithmic functions, and topics in analytic geometry. This is where you get into the fun stuff, such as parabolas, ellipses, hyperbolas, and polar coordinates. As you may have surmised, to many students, trig is deadly stuff. Only future engineers and scientists really enjoy trig, or even half-understand it at the pace it's presented in class. These videos, each tape of which corresponds to a chapter in the reference text, are just the help a struggling trig student can use. Mary Pride Chalk Dust Trigonometry covers all of a typical high-school or college trig course. (Assuming the classroom teacher makes it all the way through the book—most don't.) The course is subtitled "A Graphing Approach" (meaning you get to experience the horror of a graphing calculator), and you can purchase (which I strongly recommend) an optional reference text by that name, e.g., Trigonometry: A Graphing Approach, written by Larson, Hostetler, and Edwards. The tapes on this trig course are mostly mostly longer than those in other Chalk Dust courses. Tape 1, "Prerequisites," is almost 4 hours long.

She made D's on her first two tests in the Trig portion (of her course). She went to her professor...The professor recommended a tutor or possibly the videos that went along with the text. She immediately checked out the videos from the college library, and to our surprise, Dana was the instructor. She began watching the videos beginning with the section where she began having trouble. She spent the entire weekend watching the videos and catching up to where she was in the class. She made a 92% on her next test. Needless to say she used your videos for the remainder of the class and continued to make A's on her tests. We are all very grateful for your math videos. I recommend them to everyone I know that has children in higher math."
