select an object , or event , around that can be represented by trignometric functions then complete the following tasks , 1, describe in your own words why the object oe event chose is periodic , 2 . explain process for coming up with the functions that represent object or event . explain the point of reference chose and why chose it , how you measured or gathered the data , 3. explain a method use to veify functions are accurate 4 . reflect on the assignment . what part of the assignment find most difficut ? what find easiest / what learn while working this assignment ? determine the amplitude of the function . 6, determine the vertical translation of the function 7, use the information gathered to create a function of the form f(x)= asin (k(x-d)) +c and a funtion of the form f(x) = acos (k(x-d )) =c 8, graph functions by hand 9, using the functions that you have creatd determine the y value at the point x=period /3 and x= 5 * period /6, ( for example if your period is 4x , then x= 4x/3
