Review Information for First Midterm Exam Spring '02
The first midterm will be on Tuesday, March 12th, from 7:30 to 9:30
pm in Science Center Hall D.
No calculators or notes are allowed during the midterm, but you will
be allowed to bring in one index file card (3 by 5 inch card) with
formulas written on it if you'd like.
There will be a coursewide review held on Sunday, March 10th from 7 to
9pm in Science Center Hall E - everyone is welcome to come. Remember
also to take advantage of the Math Question Center which meets from Sunday
to Thursday from 8 to 10 pm in Loker.
Please find below a pretty exhaustive list of what we have covered
up to this point. On the midterm you should be prepared to answer
questions from any of these topics. Note that this midterm covers
material
just up through section 11.4 on the Tangent Plane - it
will not cover anything after that (i.e. it will not include sections 11.5,
11.6 and 11.7 even though we are going over them right now in class).
Also be sure to read through the list of topics that will not be included
in this first midterm (these are located at the bottom of the list).
Topics for first midterm:
-
Basic definitions for multidimensional spaces
-
Coordinate systems: rectangular, cylindrical, spherical - their use, conversion
between systems

and lines, points and planes, etc.)
-
Standard basis vectors, i, j and k and their use
-
Basic vector definitions, operations:
-
Notation: <x, y, z> = x i + y j + z k
-
Addition/subtraction, finding magnitude of vectors, finding unit vectors
-
Dot products and their geometric significance (i.e. a · b = |a|
|b| cosine(angle between a and b), finding magnitude
of a vector in terms of dot products)
-
Scalar and vector projections - computation, understanding
-
Cross products - computation and geometric significance (no scalar triple
products on midterm)

Equations of lines and planes -
-
For lines: vector and parametric equations (no symmetric equations
on page 677 section 9.5)
-
For planes: vector equations, scalar equations, linear equations
-
Normal vectors for planes, use for finding angle between planes
-
Vector Functions
-
Use in finding parametric equations for space curves
-
Ability to find and identify simple space curves and their parametrizations
- circles, helixes, parametrization of intersections (such as in example
5 on page 707)
-

-
Computation, knowledge/use of differentiation rules (Theorem 3 page 714)

Note, no integrals for vector functions on midterm (page 715 in section
10.2)

No parametrizing space curves with respect to arc length (bottom of page
718, section 10.3)
-
No Curvature computations (in section 10.3)
-
No Normal and Binormal vectors (in section 10.3)
-
Surfaces
-
Recognition of equations and traces for several simple quadric surfaces:
ellipsoids, elliptic paraboloids, cones and hyperbolic paraboloids (all
on page 691)
-
Parametric equations for surfaces - understanding of grid curves
-
Knowledge of basic examples such as for cylinders, spheres,
-
Finding parametrizations, such as parametric equations for surfaces of
rotation (page 740, section 10.5)
-
Multivariable functions
-
Depiction through use of graphs, level curves
-
Knowledge of basic examples: linear functions, cones, paraboloids, parabolic
cylinder (page 687)
-
Partial derivatives:
-
Computation (use of analytic definition, in (4) page 768, when necessary,
such as for 11.3 problem #78)
-
Geometric significance (rate of change of function in x, y direction)
-
Skip implicit differentiation (page 771 section 11.3)
-
Notation, computation of higher partial derivatives (page 772) and knowledge
of Clairaut's Theorem (on equivalence of mixed partials)
-
Skip partial differential equations section and the Cobb-Douglas Production
Function (in 11.3)
-
Tangent Planes - finding equations for, using partial derivatives
-
Use of tangent plane for approximating differentiable functions
-
Knowledge of the meaning of a differentiable function: one whose linear
approximation given by the tangent plane is a good approximation (compare
to the z = 0 tangent plane approximation for the function given in figure
4, page 782) (you do not need to know the full blown definition given in
(7), bottom of page 782)
-
Skip differentials (in section 11.4, page 784 through 786)
-
Skip tangent planes to parametric surfaces (in section 11.4)
-
Note there are a number of topics in the textbook that we did not cover
in class, and which will not be covered on the exam:
-
No scalar triple products (in section 9.4)
-
No symmetric equations (in section 9.5)
-
No integrals of vector functions (in section 10.2)
-
Nothing in section 10.3 after page 718 (starting with parametrizing
space curves by arc length at bottom of 718)
-
Nothing in section 10.4 (skipped completely)
-
No implicit differentiation (in section 11.3)
-
No partial differential equations, Cobb-Douglas Production Function (in
11.3)
-
Also, to save you a bit of worry, the following topics that we did cover
will not be tested on the midterm:
-
Section 11.2 on Limits and Continuity
-
Finding tangent planes for parametric surfaces (in section 11.4)

Answers to Review Problems for Chapters 9, 10
and 11 from our textbook:
-
Since what we've covered is a bit different from what other semesters have
covered in the past, another good way to get ready for the midterm is to
do the review problems at the end of each chapter that we've covered.
Posted below are the answers to these review problems. By doing these
review problems, you'll be able to get practise for our midterm that's
more specifically geared to what we've covered so far this semester.
-
Note that certain problems (such as #10 in review for chapter 9) are on
topics we have specifically excluded from the midterm (see list of such
topics above), so there are some problems that you shouldn't expect to
be able to do - you should be able to figure out which ones these are by
checking the list of topics covered/not covered.
-
Since we've only covered up through 11.4 in chapter 11, not all of the
answers were scanned in for that chapter, only the ones that were relevant
for us at this point.
