Equivalent Problems for the 5th Edition Text
Be sure to number your problems according to the
original assignment so the grader does not go postal on us.
Hwk Set #1
Ch 3 Review: 1, 5, (x + 1/x^2)^sqrt(7), 14, 15, 17, 35, (x tan x)^(1/5), 56.
Ch 5 Review: 16, 21, 25, 29, 30, 31, 35, 36.
12.1: 6, 10ce, 13, 17, 25, 28 but x=z not y=x, 33, 38.
12.2: 25-33.
12.3: 1, 2, <4,1,1/4>*<6,-3,-8>, 6, 7, 11, 22, 36.
Hwk Set #2
12.4: 1, 6 , 9, 13, 14, 22, 23, 27, 31, 35.
12.5: 3, 4, ?, 9, 10, 16, 17, 21, 23, 24, 27, 30, 31, 32, 35, 36, 37, 38, 65.
12.6: 3-8, 15, 16, 21-28.
13.1: 1,8, 10, <1, cos t, 2*sin t>, 17, 19-24, 25,
13.2: Use directions for 3-6 but apply to
?: r(t) = , t = -1
4: r(t) = <1+t, sqrt(t)>, t = 1
?: r(t) = sin(t)i+ 2cos(t)j, t = pi/4
6: r(t) = (e^t)i + (1/e^t)j, t = 0
13.2 continued: 9, 10, 19, 24, 35,
?? Find r(t) if r'(t)= and r(0)=<1,1,1>,
and #40 back in 13.1 = #66 in 10.7 of the new book.
Note:
Your 12.7 has been moved to a later chapter.
10.7 in the new book is 13.1 & 13.2 in your book.

I have corrected Hwk Set #3. The two blue
problems were left out.

?? = "Let r(t)=< 3sin t, 4t, 3cos t>. Starting from <0,0,3>
move 5 units of length along the curve. What is your
new position?" (#9 in original assignment is similar
to your #11, but not the same.)

Hwk Set #4
Chapter 11 in new book is chapter 14 in old book.

26, 28, 34, Draw contour map of z=x^3 - y., 39, 40, 42, 44,
make computer graph for the next three: z = e^x cos y, z = (1-3x^2+y^2)e^(1-x^2-y^2), 51.
You will need to borrow someone's book for 41-46.
