PreCalculus: Unit 4 Trig Graphs

In this unit, students will:

  • Gain a better understanding of the unit circle and its connection to trigonometric functions. ¬†Develop an understanding of the graphs of the sine and cosine functions and learn to recognize the basic characteristics of their graphs.
  • Realize transformations of y = sin(x) and y = cos(x) behave just as transformations of other parent functions.
  • Learn that the concepts of amplitude, midline, frequency, and period are related to the transformations of trigonometric functions.
  • Learn how to look at a graph of a transformed sine or cosine function and to write a function to represent that graph explore several real-world settings and represent the situation with a trigonometric function that can be used to answer questions about the situation.
