  1. 7.8 Sinusoidal Graphs

  2. Graph of y = sinx x y 1 –1 Period = 2𝝅 Amplitude = max – min = 1 – – 1 = 1 2 2

  3. General Sine Curve We’ll do c & d tomorrow If a is (+), typical sine curve If a is (–), reflect through x-axis

  4. Ex 1) Graph y = 3sinx b c a d = 1 = 0 = 3 = 0 3 –3 Amp = 3 Period = 2𝝅 Increment length

  5. Ex 2) Graph y = sin2x b c a d = 2 = 0 = 1 = 0 1 –1 Amp = 1 Per: IL:

  6. Graph of y = cosx x y 1 –1 Period = 2𝝅 Amplitude = max – min = 1 – – 1 = 1 2 2

  7. General Cosine Curve We’ll do c & d tomorrow If a is (+), typical cosine curve If a is (–), reflect through x-axis

  8. Ex 3) Graph b c a d = = 0 = –2 = 0 2 –2 Amp = 2 Per: IL: a = –2  reflect across x-axis
