SOLVED:Growing degree days The rate of development of many plant species depends on the temperature of the environment in such a way that maturity is reached only after a certain number of "degree-days." Suppose that temperature T as a function of time t is given by T(t)=15\left(1+\sin \frac{2 \pi t}{60}\right) \quad 0 \leqslant t \leqslant 60 where t is measured in days. If maturity is reached on dayt=20, what is the number of degree-days required? \left[ Hint: What are the units for \int
