WARMUP 1. Graph y = 2sin(x) 2. Graph y = cos(x) + 2 Math IV Lesson 28 • Essential Question: How are y = A sin(BѲ)+D and y = A cos(BѲ) + D graphed? • Standards: MM4A3. Students will investigate and use the graphs of the six trigonometric functions. a. Understand and apply the six basic trigonometric functions as functions of real numbers. b. Determine the characteristics of the graphs of the six basic trigonometric functions. c. Graph transformations of trigonometric functions including changing period, amplitude, phase shift, and vertical shift. d. Apply graphs of trigonometric functions in realistic contexts involving periodic phenomena. |A| = amplitude Formula for period of sine and cosine is 2∏/B D will move your graph up or down- do this last Reminder from yesterday!! New Practice Problems • Graph y = -2 sin(2x) Graph y = cos(4x) + 1
