A certain city, the temp in degrees Farenheit, t hrs after 9 am was modeled by the function: T(t)=50 + 14 sin (Pi t / 12)(adsbygoogle = window.adsbygoogle || []).push({});

Find avg temp during the period from 9 am to 9 pm.

What i did was take the Int[50 + 14 sin (Pi t / 12),t,0,9]... but this doesnt produce the answer. It says model after 9 am so at 9=0 for a , b = 10 for 9pm?

Any help?
