Any idea for these problems?

1. Average Value: The temperature ("F) in a town & hours after 9A.M. is given by T(t) = 50 + 14 sin 12 . Calculate the average temperature between 9A.M. and 9P.M. 2. Numerical Integration: The integral V1 + + der cannot be evaluated directly, and there- fore must be approximated. Using a step-size of Ar = 0.25 (that is, we are splitting the interval into 4 equal pieces), approximate the value of this integral using the specified method. (a) Midpoint Method (b) Trapezoidal Method (c) Simpson's Rule
