![]()
(a)
.
(b)
.
(c)
.
(d)
.
(e) (
is blue,
is red)
(f)
.

2-3. Draw the area represented by
. Then find
in two ways:
(a)by using Part 1 of the FTC and
(b)by evaluating the integral using Part 2 and then differentiating.
2. ![]()
![]()
(a)
.
(b)
.
3. ![]()
![]()
(a)
.
(b)
.
4-7. Find the derivative of the function using part 1 of the FTC.
4. ![]()
![]()

]
![]()
.
6. ![]()
![]()
.
7. ![]()
![]()
.
8-10. Evaluate the integral using Part 2 of the FTC.
8. ![]()
![]()
![]()
=
= (64 + 32 + 8) - (0 + 0 + 0) =
= 104.
9. ![]()
![]()
![]()

10. ![]()
.
11. Let
. Use Part 1 of the FTC to find
.
so
.
12. Give a non-polynomial function
(
) such that
and
.
For any function
set
.
Then clearly
and
so ![]()
For example
.
13. Let
and
. Find
.
and ![]()
Hence
, so
.
14. Let
defined on
. Find
.
![]()
. So ![]()
. Note that
.
and
for
. Hence
should be
.
Therefore
.
15. Let
. Find
.
Differentiate both sides to get
.
.
Hence,
.
16-17. Evaluate the integral and interpret it as a difference of areas.
16. ![]()
=
since
= 0.

17. ![]()
.

18. If
, where
, find
.
![]()
![]()
![]()
Therefore,
.
19. Find the value of
if
,
is continuous, and
.
![]()
![]()
.
20. If
is continuous and
and
are differentiable functions, find a formula for
.
![]()
