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.html http://www.mathcasts.org/gg/student/trig/sine _unit_circle_degrees_plus.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/cosi ne_unit_circle_degrees_plus.html http://www.mathcasts.org/gg/student/trig/cosi ne_unit_circle_degrees_plus.html http://www.mathcasts.org/gg/student/trig/cosi ne_unit_circle_rad.html http://www.mathcasts.org/gg/student/trig/cosi ne_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/engli sh/Roger_Moss/curve_transformations.html http://www.geogebra.org/en/upload/files/engli sh/Roger_Moss/curve_transformations.html

9. y= A sin (k Ѳ+c) + d Amplitude = (A) Period = Phase Shift =

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