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.
