Calculus
Breathing is cyclic and a full respiratory cycle from the beginning of inhalation to the end of exhalation takes about 5 seconds. The maximum rate of air flow into the lungs is about 0.5 L/s. This explains, in part, why the function f(t)=(1/2)sin((2pi*t)/5) has often been used...

calculus
In a certain city the temperature (in degrees Fahrenheit) t hours after 9 a.m. was approximated by the function T(t) = 50 + 14sin((pi*t)/12). Find the average temperature (in degrees Fahrenheit) during the period from 9 a.m. to 9 p.m. I got (1/12)((12/pi)(50(12)-14cos((pi)))+(...
