Mathematics 36, section 1 -- AP Analysis
Review Sheet for Exam 1
September 19, 1997
General Information
The first exam for the course will be given next Friday, Sept. 26, as
announced in the course syllabus. It will cover the material discussed
in class from the start of the semester it through and including
the material from Monday, September 22. There will be 4 or 5 problems,
some possibly with several parts. Some may ask for a graph or the result
of a calculation; others may ask for a precise definition of a term or
concept we have used, or a short description or explanation of some phenomenon
(similar to the questions from Lab Day assignments).
Review Session
If there is interest, I will be happy to schedule a review session outside
of class time to help you get ready for the exam. I will be available any
time between 4:00 p.m. and 7:30 p.m. on Wednesday, or any time after 4:00
p.m. Thursday (including evening).
Suggested Practice Problems
From the text:
- Chapter 1 Review Problems: p. 86-90/7, 13, 14, 26 (use what you know
about the formulas, don't just graph each of them with your graphing calculator!),
28-36, 37, 40, 42
- Chapter 2 Review Problems: p. 146-7/2 (Note: log = log_{10}
-- the idea of the problem is to approximate the derivative without using
the formula. You can gauge the accuracy of your approximation by using
the formula too!), 10,11,12,13,16
- Be able to differentiate any functions like the ones in p. 237/1 -
21, 24. (The derivative computation might come as part of a larger problem.)
Other problems:
- Imagine you are zooming in on the graphs of the following functions
near the origin:
- y = sin(x) - tan(x)
- y = ex - 1
- y = x2/(x2 + 1)
- y = x/(x2 + 1)
- y = x/(x + 1)
- y = |x| (the absolute value function).
Which of them will eventually look indistinguishable? Which would be
locally linear? For those that are, find the equations of the lines without
carrying out the zooming process.
- State the precise definition of the derivative of a function f
at x = a. Use the definition to compute f'(x) for
f(x) = 2x2 - 4, and f(x) = sqrt(x) (the square
root function).
