1. Graph
. Mark
and
on the
-axis. Using the formula for the area of a rectangle, find the function:
. Then calculate
?
2. Graph
. Assume that
and using the formula for the area of triangles (or trapezoids) find the function:
. Then calculate
.
3. Based on the graph
sketched to the left, (a) fill out approximate values in the table of
. (b) For what value of
in the interval
does
reach a minimum? (Hint 1. you see the graph of
not
. Hint 2.
is not the minimum. )
(c) Sketch an approximate graph of the area function
restricted to the interval
.
4. Use the Fundmamental Theorem of Calculus to find
.
5. Find
.
6. Find
.
7. Find
.
8. Find
.
9. (ask, discuss - and share your ideas, but no need to submit) The graph of a function
is sketched below. Sketch the antiderivative
of
defined on the interval
and such that
.
Hint: What does
represent on the graph of
?
10. Please discuss but do not submit. Share your favorite example of a function for which the related area so far function has a nice and intuitive interpreation in real life. Maybe something like the can example from the lecture.
11. Discuss it please but do not submit. Your participation in this discussion will help you understand the first part of the next lesson.
(a) Sketch a graph of
by first sketching a graph of
and by counting small squares. (b) Note that
(Why?). (c) Also, note that the FTC gives us
Why? Based on this information how can we obtain an algebraic formula for
?
