The document describes the temperature fluctuations in Sumter using a sinusoidal equation. It gives the minimum (-30°C on Dec 31) and maximum (40°C on May 2) temperatures. It then asks to sketch the sinusoidal graph, write the sine and cosine equations identifying the parameters, use one equation to predict the temperature on April 21, find the average temperature, and determine the day(s) when temperature will be 13°C.
