Question 1183667: 2) A swimmer on a floating air mattress will follow the rise and fall of the waves in the lake. When the person is on the top of the wave her feet are 1.5m above the average surface height of the lake. When she is in a trough her feet dig 0.5m into the water (-0.5m). The peaks of the waves are separated by two seconds. Create an equation of the sinusoidal function that models this movement assuming that she starts at the average surface height of the lake and heads upwards.

Could you explain me   PLEASE the meaning of this passage

        "When she is in a trough her feet dig 0.5m into the water (-0.5m)."

        and how does it relate to the problem.

Reading your post, I think it would be   MUCH   BETTER   if you write essays and post them to New Your Times
than if you create nonsensical " Math problems " and post them to this forum.
