Sine and Cosine on the same Graph

Graphing Sine and Cosine Functions  Graph the basic Sine or Cosine curve on a graph  All of the graphs will look the same as the originals, we will just adjust the labeling  Labeling the Amplitude:  The center of our graph will represent 0  The highest and lowest points will be the amplitude  Labeling the Period:  Label the y-axis as 0 and the start-over point as the period (in radians).  Find the mid-point from 0 to the period  Find the mid-point of the first and second quadrants
