D 1) Record your event through a series of photographs, a video or another appropriate method. (For example, if you are using an oscilloscope, include a photo or video of the sound wave, and a copy of the audio file that you are measuring; If you are using a website like this one: 1 @ Real-World Periodic F... X website like this one: http://astro.unl.edu/, include a screenshot, or create a video using Jing). O 2) Record the starting y-value of your object or event (when x = 0). ( 3) Find the period of the object or event. (4) Find the maximum and minimum y-values. You will need to pick a base point to reference from (usually this is a stationary object that you can measure from. For example, a stationary dock if measuring the tides).

(7) Use the information gathered to create a function of the form f (x) = asin (k (x - d)) + c, and a function of the form f (2) = acos (k (x - d)) + c. ( 8) Graph your functions by hand.

For this assignment, you may choose how you would like to present your findings. Please remember that your submission should be appropriate to the course, should be clear and easy to follow, neat and organized. See the rubric for this assignment for further details. Question 2 (1 point) 1 @ Be sure your submission answers the following questions as well: (6 pages at most, include your sources where applicable) D 1) Describe in your own words why the object or event you chose is periodic. D 2) Explain your process for coming up with the functions that represent your object or event. Explain the point of reference you chose and why you chose it, how you measured or gathered the data you need, etc. VAN Be =& (Y 9% .virtualhighschool.com
