Homework Help: trig

Posted by ske on Monday, May 4, 2009 at 8:31pm.

The average depth of water at the end of a dock is 6 ft. This varies 2 ft in both directions with the ride. Suppose there is a high tide at 4 am. If the tide goes from low to high every 6 hours, write a cosine function describing the depth of the water as a function of time with t=4 corresponding to 4AM.

My work:

y=2cos((pi/6(x-d))+6

Ok all I need help is with finding the phase shift. I am having trouble with finding it. Please be detailed. Thanks in advance
