Key Points While Watching the Video 1
1) The points on the x-axis relate to the radian measures of the unit circle. 2) A period of 2pi is the same as 1 revolution around the unit circle. 3) Pay attention to the beginning point of the sine and cosine functions. |
Key Points While Watching the Video 2
1) Pay attention to the two formulas (period and phase shift 2) Pay attention to how the amplitude changes the y-points on the graph. 3) Pay attention to how the vertical shift changes the midline. |
