Reflection: Flexibility Graphs of Sine and Cosine - Section 3: Section 3: Comparing Graphs


We ran very short on time at the end of this lesson.  I really wanted them to have an opportunity to do some comparison of the sine and cosine graph so I had list it on actual graph itself.  Here are several samples; 1, 2, and 3.  While brief, there were some important connections made like the similarity between the curves but the difference in their y-intercepts.  I think a good start was made here that we will solidify in the next lesson where we will discuss these similarities and differences as a class.
