The temperature, A, of a chemical reaction oscillates between a low of 30oC and high of 110oC. The temperature is at its lowest point when t = 0 and completes one cycle over a five-hour period. Sketch a graph of A, against elapsed time, t, over a ten-hour period. Pay careful attention to concavity and inflection points and where they occur. Find the period, the amplitude, and the midline of the graph that you drew in part a).
