Calculus essentially takes the fundamentals of algebra and extends them to include rates of change between quantities. 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. This lesson teaches students how to take derivatives of the trigonometric functions. Derivatives of sine, cosine, tangent, cotangent, secant, and cosecant are covered. In addition, several memory aids are introduced to help the student remember the relationship between these trigonometric functions. Numerous problems are worked to give the student practice with these types of problems. Teachers User Instruction & Resource Guide - Includes Recommended books & Calculus Websites.
