I'm having some trouble with applying trigonometric functions to some real life situations, particularly this one problem in my homework. Andrea, a local gymnast, is doing timed bounces on a trampoline. The trampoline mat is 1 meter above ground level. When she bounces up, her feet reach a height of 3 meters above the mat, and when she bounces down her feet depress the mat by 0.5 meters. Once Andrea is in rhythm, her coach uses a stopwatch to make the following readings: 1. At the highest point the reading is 0.5 seconds. 2. At the lowest point the reading is 1.5 seconds. Now I'm not asking anyone to do my homework as it would defeat the whole purpose of me learning, but I would certainly love some advice as to how to formulate an equation and graph for this particular problem. One such problem I have with the problem is figuring out where the graph begins on the y-axis, or in other words, how high she is when the coach starts timing her. Any help would be greatly appreciated. Thanks.
