1. 4.2 Double Integrals: Volume and Average Value

Theorem 4.12. Average Value of a Two-variable Function. Let $f(x,y)$ be a continuous function defined over the rectangle \( ...
Consider a surface $f(x,y)\text{.}$ In this section, we are interested in computing either the volume under $f$ or the average function value of $f$ over a certain area in the $x$-$y$-plane. You might temporarily think of this surface as representing physical topography—a hilly landscape, perhaps. What is the average height of the surface (or average altitude of the landscape) over some region?

In calculus, you can find the average value of a function by using the mean value theorem for integrals. Here's how to do it.

We might also want to compute an average not tied to speed; for example, what is the average height of the curve sin(πt) over the interval [0,1]? Is it the same ...
The average of some finite set of values is a familiar concept. If, for example, the class scores on a quiz are 10, 9, 10, 8, 7, 5, 7, 6, 3, 2, 7, 8, then the average score is the sum of these numbers divided by the size of the class: $$ \hbox{average score} = {10+ 9+ 10+ 8+ 7+ 5+ 7+ 6+ 3+ 2+ 7+ 8\over 12}={82\over 12}\approx 6.83. $$ Suppose that between $t=0$ and $t=1$ the speed of an object is $\sin(\pi t)$. What is the average speed of the object over that time? We know one way to make sense of this: average speed is distance traveled divided by elapsed time. The distance traveled is $\ds\int_0^1 \sin(\pi t)\,dt=2/\pi\approx 0.64$, and elapsed time is $1$, so the average speed is $2/\pi$. This appears to have nothing to do with the simple idea of average, as in the case of the quiz scores. We might also want to compute an average not tied to speed; for example, what is the average height of the curve $\sin(\pi t)$ over the interval $[0,1]$? Is it the same as the average speed? More generally, can we make sense of the average of $f(x)$ over an interval $[a,b]$?
