  2. Section 4.5: Graphs of Sine and Cosine Functions. Pages 321 - 331 What you should learn • Sketch the graphs of basic sine and cosine • functions. • Use amplitude and period to help sketch the • graphs of sine and cosine functions. • Sketch translations of the graphs of sine and • cosine functions. • Use sine and cosine functions to model real-life data.

  6. Amplitude and Period

  7. Reflection The graph of y = -f(x) is a reflection in the x-axis of the graph of y = f(x) thus,

  8. Translations of Sine and Cosine Curves The constant c in the general equations y = a sin(bx – c) and y = a cos(bx – c) creates a horizontal translation (shift) of the basic sine and cosine curves.
