Ch 7 Review and the Answer Key

2010-01-19T18:44:00.003-05:00

The answer key to the Review/Extra Problems can be downloaded here. Remember, the snowflake problems won't hurt but are not due until Monday.

Please note: there is a typo in the integral formula for problem 4a. It should have the sine inverse of u over a (not u over 2).

Applications of the Definite Integral

Slope Field Generators

2009-12-19T15:03:00.003-05:00

A slope field is a graphical method for solving differential equations. While you will be required to generate then by hand, usually we want to just look at them. There are several ways to generate them electronically:

Calculator: Download slopefields.zip from http://www.ticalc.org/pub/83plus/basic/math/calculus/
There are seven (!) slope field programs but this one seemed the easiest to use (and
get out of). It is the one dated 05-07-01.

Computer Applet: http://alamos.math.arizona.edu/~rychlik/JOde/JOdeApplet.html

Mac Application: http://www.colby.edu/personal/s/sataylor/teaching/F08/MA121/SlopeFields.pdf

You want to have something on your calculator by Monday (the 21st). You need the cable that connects your calculator to the computer or (if you have a friend that has successfully downloaded the program) a cable to connect your calculator to a friends calculator. You can also type the program into the calculator.

Separation of Variables HW

2009-12-15T15:07:00.001-05:00

Download the pdfs of the pages for the homework: (first page) - (second page). (Mr. Harris and I were unable to combine them - stupid computers!)
They are scans from section 11.4 of the third edition of Calculus by Hughes-Hallett, Gleason, McCallum, et al.
Do problems 3-33 by 3s, 35, 36, 39-41

Chapter 6 - The indefinite integral, and differential equations

2009-12-03T15:38:00.008-05:00

Just as we sometimes want to know the slope of a curve at a certain point (call it the definite slope), we also want to know the slope of a curve just anywhere - the slope formula (call it the indefinite slope). Well, the same goes for the integral. Chapter 5 was on the Definite Integral and Chapter 6 is on the Indefinite Integral. We will learn how to find it algebraically, graphically and numerically (of course). The algebraic portion will take some time and you will be subjected to almost daily quizzes to make sure you are getting it.

Answers to today's extra questions

2009-10-19T15:35:00.002-04:00

1. For the ellipse problem today (4x^2 + 9y^2 = 36) with the generic first quadrant point (p, q), you should find the following:

xT = 9/p
yT = 4/q
xN = 5p/9
yN = -5q/4

Given that p goes from 0 to 3 and q goes from 0 to 2, we can say the following about possible values of the tangent and normal intercepts:

xT = (3, infinity)
yT = (2, infinity)
xN = (0, 5/3)
yN = (-5/2, 0)

2. For e^(2x) = k*sqrt(x) then it happens at x = 1/4 when k = 2/sqrt(e
(if you need a hint, you have two equations (original and slopes) for the two unknowns (k and x))

You homework is to take a peak at the Chain Rule - the last of our derivative rules. Read section 3.6 and do p.146-147/1-27 odd. I will prove it tomorrow.

Questions from today's handout

2009-10-01T20:07:00.002-04:00

You may have already noticed but at the top of today's handout of problems it mentions that you can get worked solutions for the odd problems from www.CalcChat.com (though you may need to download Shockwave to use it).

I noticed also that problem 6 is really a Chain Rule problem (sneaky cx) so you can skip that one.

Here are my answers for the even problems:
2. y - 4 = 4(x - 2) and y - 1 = -2(x + 1)
4. a] tangent y - 4 = 4(x - 2)
    b] normal   y - 4 = =0.25(x - 2)
    c] y = 0
    d] normal = curve: y = (-1/2a)(x - a) + b = x^2 (where b = a^2)
         if you use the quadratic formula to solve for x you find the
          discriminant is positive so there are two solutions.
6. skip it
14.a] v = (-27/5)t + 27 and a = -27/5
    b] v = 27(1 - .2t) = 0 so t = 5
    c] a = 5.4 ft/sec^2 rather than 32 ft/sec^2, about 1/6^th

The first half of Chapter 3

The computer lab deals with rate of change using actual data recorded by Mr. Richardson when he used to ride his bike from his old apartment in Bedford.

http://lhs.lexingtonma.org/Teachers/Kelly/calcbc/bikeride/

The link is to a page of Mr. Kelly's. His page mentions that the directions were handed out in class. I am going paperless with this. You will open the directions, type your answers directly into the document, and email it to me, along with any other work required. Please use a different font or color so it is easy to find your answers.

Welcome!

2009-09-01T20:58:00.002-04:00

Welcome to BC Calculus. This year we will do two semesters of college calculus by May 5th, 2010 (the date of the AP Exam). After that we will do some other fun things because the math never ends...

This class goes very quickly so there are many homework problems each night, certainly more than you want to do the night before a test. KEEP UP!!! We learn lots of cool stuff and you don't want to waste time not understanding it.
