Presentation Transcript

  1. Sin & Cos Graphs

  2. Let’s explore the sine graph! • http://www.mathcasts.org/gg/student/trig/sine_unit_circle_degrees.html • http://www.mathcasts.org/gg/student/trig/sine_unit_circle_degrees_plus.html

  3. y = sin Ѳ 0

  4. Let’s explore the cosine graph. • http://www.mathcasts.org/gg/student/trig/cosine_unit_circle_degrees_plus.html • http://www.mathcasts.org/gg/student/trig/cosine_unit_circle_rad.html

  5. y = cos Ѳ 0

  6. Let’s graph it on the calculator. • Make sure the calculator is in radian mode • Type sin(x) in y1 • Press zoom trig • Now let’s look at y = cos(x).

  7. Transformations of Sine & Cosine Graphs

  8. Transformation of sine • http://www.geogebra.org/en/upload/files/english/Roger_Moss/curve_transformations.html

  9. y= A sin (kѲ+c) + d • Amplitude = (A) • Period = • Phase Shift =

  10. Write the equation of the sine function with the following features. • Amplitude = 5 • Period = 90° • PS = 4°

  11. Write the equation of the sine function with the following features. • Amplitude = 4 • Period = • PS =
