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.

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.
