  1. Steps for Graphing Sinusoidal Functions Determine the phase shift Graph Sinusoidal functions Find a sinusoidal function from data

  2. sine and cosine functions Amplitude= │A│ Period = 2π/B Phase Shift = C/B D = (max+min)/2

  3. Steps for Graphing Sinusoidal Functions • Determine the amplitude and period of the function • Determine the starting point of one cycle of the graph • Determine the ending point of one cycle of the graph • Divide the intervals into four subintervals each of the length the period/4

  4. Graphing 5. Use the endpoints of the subintervals to find five key points on the graph 6. Fill in one cycle of the graph 7. Extend the graph in each direction to make it complete

  5. Steps for fitting Data to a sine function • Determine the amplitude = max-min/2 • Determine D, the vertical shift= max+min/2 • Determine B= 2π/P • Determine the horizontal shift of the function by solving the equation • Y=A sin (Bx-C)+D • THE END
