We have now graphed both Sine and Cosine using the pasta to illustrate the shape of the graphs.
Review the following animation from Desmos to further clarify how we achieved this.
Helpful Hints:
- To view the sine graph, click the open circle next to "Sine Animation"
- To view the cosine graph, be sure to have unchecked the sine graph and click the open circle next to "Cosine Animation"
Refer to the "Questions to Answer" portion at the bottom of the blog and answer questions 1, 2 and 3 on a separate piece of paper.
Access a second animation of Desmos by the following link:
Refer to the "Questions to Answer" portion at the bottom of the blog and answer question 4.
Questions to Answer:
Bring your answers with you to class tomorrow on a separate piece of paper
1) List at least 5 similarities between the graphs of sine and cosine.
2) List at least 5 differences between the graphs of sine and cosine.
3) Discuss the derivation of the graphs of sine and cosine, and why they are similar in shape?
4) Sine and Cosine are Trigonometric Functions, which means they are from the study of triangles, specifically right triangles. How does this information (right triangles) help us explain the horizontal (left and right) shift between the two graphs?
