Exam 1 Date: 10/23 Friday Time: 2:00-2:50pm
Exam 1 Information Section 1.4 – Section 2.4, Maple Absolutely no share of calculators. Bring
extra batteries, extra calculators. It is your responsibility to bring a workable calculator.
Do not store any information in your calculator.
You are expected to use correct notations.
Major Themes Slope of the tangent line at a point on a graph can be
approximated by a limiting process. (The same apply to other rate of change problems in physical sciences.)
The derivative of at a point :

Important Concepts Left-hand limits and right-hand limits. exists if is continuous at a point if is differentiable at a point if exists
lim ( )x a
f x
lim ( ) lim ( )x a x a
f x f x
lim ( ) ( )x a
f x f a
Important Skills Evaluate limits by using algebra (not
estimate) Finding derivatives using limits and
formula
Expectations Must show the “formula” step when using
the product/quotient rules

Major Theorems Squeeze Theorem (Know the statement
and how to apply) Intermediate Value Theorem (Know the
statement) If is differentiable at a point , then is
continuous at (Know the statement and able to point out places where is not differentiable)

Cheating… It is a violation of SPU community
standards of behavior.

Front Matter Make sure you put down the details of
the solutions. No points will be given to answers alone.
No points will be given to graphs or graphical solutions.
Make sure your work is neat, clear and easily readable or you will receive NO credits.
Front Matter Make sure your solutions are complete
and logically presented. Do not skip steps.
Check and Recheck your solutions. Be sure to cross out any scratch works or unwanted materials.
If more than one solution is given, no points will be given to that problem.
Front Matter Points will be taken off for bad notations
or omission of notations. The same mistake can be penalized for multiple times.
If you use the result of a theorem, make sure you state the name of the theorem to justify your solutions.
Allocate your time wisely.
