Today we're looking at section 6.2: Setting up integrals: Volume, Density,
Average Value. What questions do you have about this topic, or any of our
previous topics?
The difference in area between two curves
The last lab
Substitution
Net change as the integral of a rate
The Fundamental Theorem of Calculus, Part II
The Fundamental Theorem of Calculus, Part I (it's really that easy!)
anti-derivatives
Definition of the Riemann sum (a function of three variables! See p. 262).
Definition of the definite integral.
Properties of the definite integral.
Summation formulas
Limits of summations (power sums)
Putting these formulas into your calculator.
???
I'd like to take a little time to work a couple of examples: one standard, the other not so much.
A standard volume problem
An interesting traffic problem
In both cases, the problem comes down to figuring what you want to "add up", in an integral of the form
Next 25 minutes:
You will undertake the following activity: Setting up integrals
For the final 20 minutes, we'll switch to a class discussion of the
proposed solution(s).
