Cabrillo HS student, Valentina, shows how to find the Amplitude and
Period of a Function. Questions this video answers How do I find
the period of a function? How do I use this to graph sine and cosine
functions? What are the coefficients of sine and cosine equal to?

Valentina does a nice job explaining the steps she is taking to solve this problem. I like that she uses the many terms associated with this problem so students can get used to using the proper terms. Her work was fairly easy to follow; the work solving for the period could be more organized. I like that she simplified the problem by explaining that the amplitude is the leading coefficient and the period can be found by using the coefficient before the x. A graph would have been helpful in clarifying this information as well as solidifying the information for students to remember.

 In this video, I really appreciate that Valentina explains the concept with such great detail. The concept is rather straight forward, but she does a great job explaining the steps of her example. I think it would be helpful to give a little more background information such as equations.

Excellent video! Each step was walked through with good detail and thoroughly explained. It would have been helpful if the formulas for amplitude and period were written out, but it was still easy to follow with an explanation.
