Graphing Sine and Cosine Functions (Includes All Transformations)

In the apps below, note the trigonometric function displayed. Your goal is to graph one period of this function correctly. Once you do, you'll see a Correct !!! sign appear. For the period you graph,
  • Enter the START VALUE in the start input box (right side).
  • Enter the END VALUE in the end input box (right side).
  • Enter the x-coord's of the 3 key points in between start and end: ( , , of the way in this period).
  • If need be, adjust the xscale and yscale.
  • Move the LARGE POINTS that appear to graph correctly.
