The rate at which contaminated water enters a treatment
tank is E (t)= 2000 +650cos (pit^2/10)
gallons per hour, for 0 ?t ?6 hours. How many
gallons of contaminated water enters the tank during the 6 hours? Give you answer to
the nearest integer.

Solution
water entered=2000+650cos(pi t^2 /10)dt
=2000t+6505cos(t/5) from t=0 to 6
=12561.4 gallons
