Special angles and exact value are also covered. This lesson will show you how to: - find the reciprocal ratios of an acute angle - use your calculator with cosecant, secant and cotangent - use cosecant, secant and cotangent to solve problems - work with special angles (30, 45 & 60 degrees) and exact values (values obtained without the use of a calculator) This lesson contains explanations of the concepts and 15 example questions with step by step solutions plus 4 interactive review questions with solutions. The following lesson will help you with the fundamentals of this lesson: - 300 Basic Trigonometry Part I (http://www.mindbites.com/lesson/5125)
