During a storm, waves pass a fixed point every 2s. The difference between the crest and the trough of any wave is 5.2m a) Write the equation of the sine wave that models the height of a point on the water wave. b) Graph using 0m as the trough My Answer: 2Pi / k = 2 k = Pi 2.6sinPi(x) I wanted to check if this is correct? I just wanted to make sure I was not supposed to shift vertically 2.6m? i.e. 2.6sinPi(x) + 2.6 Originally I vertically shifted it 2.6 but then I couldn't figure the reason I did this (other than not going negative m). Then when I noticed part b said the trough is 0m I corrected my equation not to include the shift.
