Homework Help: Trigonometry

Posted by Allison on Saturday, January 1, 2011 at 4:09pm.

Sketch a height versus time graph of the sinusoidal function that models each situation. draw at lease three cycles. assume that the first point plotted on each graph is at the lowest point:

a girl lying on a an air mattress in a wave pool that is 3 m deep, with waves 0.5 m in height that occur at 7 s

i was just wondering if i would start off at -0.5 m, and then at 3.5 s, i would plot at point at 0.5 m, and then at 7 s, i would plot at point at -0.5 again? in that case would 7 be considered the period of the function?
