Trigonometry and Pre-Calculus are essential topics in mathematics that are needed to bridge the gap between Algebra and Calculus. Attempting to tackle calculus without a mastery of Trigonometry will almost certainly lead to frustration. This series covers essential subjects in Trigonometry and Pre-Calculus with exceptional clarity so that students will feel well prepared to move onto Calculus and Physics. The Trigonometry Tutor Series is a complete 9 lesson series covering all of the core topics in detail. What sets this series apart from other Trigonometry teaching tools is that the concepts are taught entirely through step-by-step example problems of increasing difficulty. It works by introducing each new concept in an easy to understand way and using example problems that are worked out step-by-step and line-by-line to completion. If a student has a problem with coursework or homework, simply find a similar problem fully worked on in the series and review for the steps needed to solve the problem. Students will be able to work problems with ease, improve their problem-solving skills and understand the underlying concepts of Trigonometry.
