This unit consists of 4 topics: Graphing the sine, cosine, secant, cosecant, tangent, and cotangent functions. Then we will apply the sine and cosine functions to real world application problems where you will have to write the sine and cosine function that best represents each application. The first lesson will go over how to graph the sine and cosine functions and then move through the other four trig functions. You will find worksheets that will help you judge your understanding of each lesson. After completing the worksheets, you will need to take the assessment quizzes. After you have completed each quiz with a grade of 80% or higher, then you are ready for the test.
