The given function is
![f(t) = 33 sin( \frac{ \pi }{2} t) - 20](https://tex.z-dn.net/?f=f%28t%29%20%3D%2033%20sin%28%20%5Cfrac%7B%20%5Cpi%20%7D%7B2%7D%20t%29%20-%2020)
with
t = time, hours
f = temperature, °C
Because the maximum and minimum values for the Sine function are +1 and -1 respectively,
The maximum value of f = 33 - 20 = 13.
The minimum value of f = -33 - 20 = -53.
The period, T, is given by
![\frac{2 \pi }{T} = \frac{ \pi }{2} \\ \\ T=4](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%20%5Cpi%20%7D%7BT%7D%20%3D%20%5Cfrac%7B%20%5Cpi%20%7D%7B2%7D%20%5C%5C%20%5C%5C%20T%3D4)
