document.write( "Question 1150036: The tide on a certain shore on a planet has a period of 36.5 hours, and the high tide level is 8 m above the low tide level. At t = 0 the water level is 2 m above the low tide level and rising. Using trigonometric functions, find a function to describe the height H(t) of the water above the low tide level \n" ); document.write( "
