View Finding a particular F(x), given initial conditions (xo, yo)

*Integration catch-up:* Know rules of antidifferentiation, pp 237-238 (basically the same as video and handout/pdf above)

Read Sec 33, Finding a Definite Integral

**Tues Nov 28** This week we cover the Fundamental Theorem of Calculus.

There are two parts to this theorem. We generally use the second part, which is what we need to find the value of a definite integral. To that end, watch Fundamental theorem of calculus part II

(The theoretically deeper but fascinating Fundamental Theorem of Calculus Part I is at the video link)

View Patrick's definite integral examples:

Example 1 of finding a definite integral

Example 2 of finding a definite integral

Do p 260 #1 a-e i j k o p q

Finally, read Sec 34, Definite Integral and Area.

Then view this important video: Finding area between two curves

** Last set practices **

Read Sec 35. This is a DENSE section that covers far more than the title suggests.

The road map:

- Riemann sum (area of rectangles of ever-increasing number approaches the area under the curve, i.e., the definite integral;

- average value of a function, which is neat because it tells us what value the function attains on an interval via the definite integral divided by the width of the interval;

- total value of a function, which is basically the FTC applied to a marginal or other rate function, whose antiderivative is the sought after function, say cost fcn, value fcn, any quantity given a rate of change of that quantity;

- present and future value of an investment through a constant flow of money (“income stream”) at continuous compounding (this is the analogous case to the Sec 5 topic of present and future value of a one-time investment).

View Average value of a function

The average value of a function is actually the mean value theorem of integration.

Read the rest of Sec 35, on Present and Accumulate (Future) Value of an Investment.

The difference from the Sec 5 topic, as I've said, is now we consider a continuous flow of money (an income stream, like an investment or a business venture).

Do p 278, all. The ones I have solutions prepared for are #1 a, d, 2, 4 a, 6-9, 11, 12, 15.

Solution to Quiz 10 is here

Solution to the take home quiz is here

**Sunday Dec 10** There will be a review session in LH 012 on Sunday Dec 10 from 1:00 pm - 3:00 pm.
