The mechanics of calculation, by hand, calculator, or computer are still important, but not in and of themselves. They are tools.

There is no such thing as a stupid question. Yell them out!

If something confuses you, raise you hand and shout out to the world that the person sitting next to you doesn't understand! :-)

If you have not had Calculus before, that is also OK. Rest assured that this course does not presume any knowledge from AB or BC calculus.

Some problems:

Some answers to the quiz (November 5) 1. A spherical ball 8" in diameter is coated woth a layer of ice of uniform thinkness. If the ice melts at a rate of 10 cubic inches per minute, how fast is the thinkness of the the ice decreasing with it is 2" think?

Let x be the thinkness of the ice. The radius of the iron ball is 4, so that the total volume is: V = (4/3) pi (x + 4)^3 Differentiating gives: dV/dt = 4 pi (x + 4)^2 dx/dt Plugging in numbers: -10 = 4 pi (2 + 4) ^2 dx/dt or -10/(4 pi 36) = dx/dt3. A balloon is 200 ft off the ground and raising vertically at a constant rate of 15 ft/sec.. An automobile passes beneath it traveling at 66 ft/sec. How fast is the distance between them changing 1 second later?

Let r be the distance between them, h the height of the balloon, and x the distance the car travels. Then r^2 = h^2 + x^2 Differentiating, 2 r dr/dt = 2 h dh/dt + 2 x dx/dt One second later x = 66, h = 200 + 14 = 215, so r = Sqrt(215^2 + 66^2). Plugging in numbers gives: 2 Sqrt(215^2 + 66^2) dr/dt = 2 215 15 + 2 66 66 or dr/dt = (6450 + 8712)/ (2 Sqrt(215^2 + 66^2)) which is about 33.7

These are Maple files. If you have enough memory you can set (in preferences) that Maple is the helper app for files with suffix ".mws". Then when you click on the following, Maple will start up with the assignment. Save the file on your own computer, and start....

Some solutions to quiz #3:

1. Suppose the f'(x) = f(x), and that f(g(x)) = x. Find g'(x)

Solution: Take f(g(x)) = x, and differentiate useing the chain rule, giving: f'(g(x)) g'(x) = 1 But f'(junk) = f(junk), so: f(g(x)) g'(x) = 1 Using f(g(x)) = x, we get: x g'(x) = 1 Giving g'(x) = 1/x.

3. The radius of a certain sphere is increasing at a rate of 4 inches per minute. If currently the radius is 5 inches, how fast is the volume increasing?

V = (4/3) pi r^3, so differentiating with respect to t, we get: dV/dt = 4 pi r^2 dr/dt. Plugging in r = 5, and dr/dt = 4, we get the answer dV/dt = 4 pi 5^2 4 = 400 pi

4. Find the equation of the norml line to the curve x^2 y^2 + xy = 5 at the point x =1, y =2.

Differentiating the euqation gives: 2 x y^2 + 2 x^2 y dy/dx + y + x dy/dx = 0. Solve for dy/dt, giving: - 2 x y^2 - y dy/dt = -------------- 2x^2y + x Plug in x = 1, y = 2 and get: - 2 1 2^2 - 2 dy/dt = -------------- 2 1^2 2 + 1 = -10/5 = -2 So slope of the normal is -1/(-2) = 1/2. Equation is therefore (y-2) = (1/2) (x-1)

Some problems on the chain rule, power rule, trig functions:

Solutions to Quiz #2. For compatibility and for ease of loeading, I am attempting to do these in plain text. When I get mathematica working again, I will begin to post solutions to quizes in html + gifs.

Problem 1: (10 points) Calculate the derivative of (3x)^(1/2) by the definition.

Solution: We compute the limit: (3(x + h))^(1/2) - (3x)^(1/2) lim --------------------------- h->0 h Multiply the numerator and denominator by (3(x + h))^(1/2) + (3x)^(1/2): (3(x + h))^(1/2) - (3x)^(1/2) (3(x + h))^(1/2) + (3x)^(1/2) lim --------------------------- --------------------------- = h->0 h (3(x + h))^(1/2) + (3x)^(1/2) (3(x + h)) - (3x) lim ------------------------------ = h->0 h (3x + h)^(1/2) + (3x)^(1/2) 3h lim ------------------------------ = h->0 h (3x + h)^(1/2) + (3x)^(1/2) 3 lim ------------------------------ = h->0 (3x + h)^(1/2) + (3x)^(1/2) 3 ------------------------ = (3x)^(1/2) + (3x)^(1/2) 3 ------------- = 2(3x)^(1/2)

Problem 2: 5 points each. I'll just give the answers.

Solutions: a) 4 x^3 sin(x) + x^4 cos(x) b) (4 x^3 + 6 x^2 + 4) (3x^2+x^6) - (x^4 + 2 x^3 + 4 x)(6x + 6 x^5) ------------------------------------------------------------------ (3x^2+x^6)^2 c) (4 x^3 + 6 x^2 + 4)(sin(x) + 42) - x^4 + 2 x^3 + 4 x)(cos(x)) ------------------------------------------------------------- (sin(x) + 42)^2

Problem 3: Find the tangent line to the curve sin(x)/6x at the point x = pi/3.

Solution: Let f(x) = sin(x)/6x, therefore the tangent line goes through the point x = pi/3, y = f(pi/3) = Sqrt(3)/2. f'(x) = cos(x) 6 x - 6 sin(x) --------------------- (6x)^2 So f'(pi/3) = (1/4 pi) - (3/4) Sqrt(3)/pi^2 So we get y - Sqrt(3)/2 -------------- = (1/4 pi) - (3/4) Sqrt(3)/pi^2 x - pi/3 This can be simplified, if you like.

WIll cover up through 1.5,1.6,2.5,2.1,2.2

Things to know for the quiz:

- Definition of the derivative and using it.
- Diferentiation rules, up through qutient rule.
- Using the derivative, e.g., rates of change, tangent lines and their slopes, finding where the tangent is horizontal, etc.,etc..

As I said yesterday, I will be arround this afternoon from about 3 to about 4 pm. In my office (Skiles 263) or if I'm not there, check the door of my office. This will say where I am.
