Question

I need help with question 6, I've included the prior answers from questions 1, 2 and 3 to help you. I've also included what the previous questions were so you have some context of the situation. Although, I think you only need the answers from part C ( which is the graph I've including) to answer question 6

Answer 1

Question 6 asks us to determine the period of the function.

Looking at the height of the blade tip, it varies in a sinusoidal manner.

Thus, the period is the distance between successive same heights on the table.

The function takes 360 degrees to return to its same value. At angle zero, the height was 150ft and it was still 150 ft at 360 degrees.

Thus the period is 360 degrees.
