Mathematics 133 -- Intensive Calculus for Science 1
Quiz 5
October 17, 2001
This week, we are back to our regular five-day schedule.
The fifth regular quiz of the semester will be given in class on
Friday, October 19. It will cover the material from sections
2.4, 2.5, and 2.6 from this week's problem set. You may
use a calculator on this quiz (but I'd be surprised if you
found you needed one!). The specific topics
to be covered will be:
- The derivative function f'(x) for a function f(x).
Know:
- How to spot points on a graph where f'(x) = 0,
where f'(x) > 0 (intervals where the function f
is increasing), and where f'(x) < 0 (intervals
where f is decreasing).
- How to compute a simple example (say a degree 2 polynomial function,
or f(x) = 1/x, etc.)
from the limit definition of f'. (See section 2.4 problems 13-16)
- How to sketch y = f'(x), given the graph y = f(x)
(See section 2.4/23 - 30)
- The derivative as rate of change, the units of dy/dx,
interpreting statements about dy/dx (like Section 2.5/1-4,11-14)
- The second derivative f''(x), its relation to concavity
Know
- How to identify
where f''(x) > 0 (intervals where the graph y = f(x)
is concave up, or f'(x) is increasing), and
where f''(x) < 0 (intervals where y = f(x) is
concave down, or f'(x) is decreasing). (See Section 2.6/1-4.)
- The interpretation of the second derivative as acceleration.
On the quiz, there will be three
questions similar to problems from the assignment.
