Guidelines in reviewing for Exam 1
Exam 1 will cover material we have gone over in the course from
Sections 2.1-2.2, 2.4-2.7, and 3.1-3.4.
Following is a list amassing together the daily goals
for days covering material tested on Exam 1. In studying for
this exam, you are of course encouraged to look over class notes
and examples, homework (don't just look over your past write-ups;
try to re-work a smattering of assigned problems from
scratch) and problems from the Practice Exercises
sections at the ends of chapters. You should also assess your
readiness for the exam based on the list of goals.

- Give a definition for vertical/horizontal asymptotes that
involves a limit.
Note: The discussion of oblique asymptotes (Example 9,
p. 101) may be ignored.
Goals for Class Date: Sept. 13, 2007
Students should be able to
- relate the criteria necessary for the statement the function
f is continuous at x = a to hold.

use of continuity when evaluating limits.

continuous functions.
Goals for Class Date: Sept. 17, 2007
Students should be able to
- state the intermediate value theorem.
- recognize situations in which existence of a
solution is all that is sought.
- apply the intermediate value theorem correctly.
Goals for Class Date: Sept. 18, 2007
Students should be able to
- write down an appropriate formula for the derivative of
a function at a point, and explain what it means in
terms of slope.
- recognize the various notations for the derivative,
along with their meanings.
- use the definition of derivative to compute the
derivative function, for a given f.
- find the slope of a given curve at any specified
location, or explain why no such slope exists.
They should be able to write equations of tangent
lines when it is desired.
- recognize (from among a list of graphs) the graph
of the derivative function, when f is known.
Goals for Class Date: Sept. 19, 2007
Students should be able to
- state the following derivative rules: sum rule, difference rule,
constant multiple rule, product rule, quotient rule, power rule
- find derivatives for sums, differences, products and quotients
of monomials using these rules.
Goals for Class Date: Sept. 20, 2007
Students should be able to
- recognize blatant points of non-differentiability on a graph.
- determine the general shape of the graph of f '
from the graph of f.
- learn how to differentiate ex, and
various functions made from sums, differences, products
and quotients of monomials and exponentials.
Goals for Class Date: Sept. 24, 2007
Students should be able to
- interpret the derivative f ′ as slope on the
graph of f.
- interpret the derivative physically as a rate of change,
particularly when the independent variable of the function
is not time.
- interpret the 2nd derivative as a rate of change of the
rate of change; in particular, when the independent variable
is time and the dependent variable is position, the 2nd
derivative is acceleration.
Goals for Class Date: Sept. 25, 2007
Students should be able to

- find derivatives for expressions involving sums, differences,
products and quotients of trigonometric functions, polynomials,
and exponential functions.
