2002 AP Calculus AB #1

There are no points of
intersection, but we are
given an interval from
to x = 1
In order to find the area
of a region enclosed by
two graphs, we must use
the following formula
where f(x) represents
the upper
function ,
and g(x) represents the
lower function ,
a is the upper limit ( )
b is the lower limit (1)
The answer, when the equation is plugged in the
calculator is 1.22
y = 4
In order to find the volume of the solid revolved around y = 4
we must use the Washer Method
R =
r =
When all the information is plugged into the formula, we get:
The R and r are determined in accordance to the line around which the
graph revolves (y = 4). R is the outer ring (further from the line), while r
is the inner ring, meaning that it is closer to the given line. Also, the
specific line must be included in the formula if it is anything but y = 0.
Answer: 23.609
First find the derivative of h(x)
and set it equal to zero in order
to find the critical values
An absolute minimum and
maximum occur at either the
critical point or at one of the
endpoints, meaning we must
find h(x) values for all of them
and test which is the lowest one
x = 0.567143
x h(x)
1/2
0.567143
1
Absolute minimum value:
h(0.567143) = 2.330
Absolute maximum value:h(1) = 2.718
