Let W = f(u) be the temperature, in °C, of a chemical reaction u hours after the reaction starts. The temperature varies sinusoidally and oscillates between a low of 30 °C and a high temperature of 110°C. The temperature is at its highest point when u = 0 and completes a full cycle over a 4-hour period. a. Find the amplitude, midline and period of f(u). The amplitude of f(u) is The midline of f(u) is The period of f(u) is b. Find a formula for the sinusoidal function W = f(u). f(u) = °C. °C. (Note: you should give an equation for the midline as your answer.) hours.
