AP Calculus AB Day 10 Section 4.4 Perkins
The Mean Value Theorem for Integrals Gives the average value of f(x) on [a,b].
1. Find the average value of on [1,4]. Then find where f(x) obtains this average value. This value is obtained when…
Second Fundamental Theorem of Calculus In order to use this shortcut we must have… a derivative… of an integral… whose lower bound is constant… and whose upper bound is a function of x.
We don’t know how to integrate this function! Using the 2nd Fundamental Theorem of Calculus:
