decreasing for x > 1/ √3 (except, of course, where f(x) is undefined at x = −1, 0, +1). It is
clear from the form of the derivative that x = −1/ √3 is a local minimum and x = +1/ √3 is
a local maximum. The second derivative is,
The numerator is a quadratic equation in x2. However, there are no real solutions of the

22. In particular, y = f(x) is asymptotic to the line y = 2x as x goes to ±∞. Also, f(x) is an
odd function that clearly has an inflection point at (0, 0). The derivative is,
Thus the critical points are x = − √3, x = 0 and x = +√3. The function is increasing for x
< − √3, it is decreasing for − √3 < x < −1, it is decreasing for −1 < x < +1, it is
decreasing for +1 < x < + √3, and it is increasing for x > + √3. Therefore x = − √3 is a
local maximum, and x = + √3 is a local minimum. Finally, the second derivative is,
In particular, the only inflection point is x = 0. The function is concave down for x < −1, it
is concave up for −1 < x < 0, it is concave down for 0 < x < +1, and it is concave up for x

The area of the corral is,
mathsassignmenthelp.com
25. Choose b as the independent variable. From the constraint equation,
Since a must be between 0 and b, the endpoints of b are b = L/4 and b = L/2. Substituting 2b
− L 2 for a in the equation for A gives,
Differentiating
Thus the only critical point is at b = L/2, which is also an endpoint. This gives a local
maximum for A,
The value of A at the other endpoint is,

is decreasing at the rate,
Therefore the length is decreasing at the rate,
mathsassignmenthelp.com
27. To summarize, the length of the icicle is decreasing at the rate,

Also, the area of the 5 exposed sides is
By hypothesis, the rate of change of the volume is proportional to the area of the exposed
sides, i.e.,
for some constant C. Differentiating gives,
Substituting gives,
mathsassignmenthelp.com
28. But this is just another constant. Because dx/dt is a constant, x(t) is a linear function,
x(t) = x0 − at,
for some constant a. By hypothesis, V (x(5)) = V (x0)/2. Solving gives,

unique point x such that,

Solution to 5.3 Using the shell method, the infinitesimal volume of a shell with inner
radius x, outer radius x + dx, and height y = b sin(x/a) is,
dV = 2π(radius)(height)(width) = 2πxydx = 2bπx sin(x/a)dx
Therefore the total volume equals,
To compute this integral, use integration by parts
This gives,
mathsassignmenthelp.com
37. For the second integral, notice that cos(x/a) is positive for 0 < x < aπ/2, and then for
aπ/2 < x < aπ, cos(x/a) is the negative of cos(x/a) on the first interval. Therefore the
integral from 0 to aπ/2 cancels exactly the integral from aπ/2 to aπ. Therefore,
Observe that the volume of the cylinder with base radius aπ and height b is π3a2b. Thus
the fraction of the volume of the cylinder taken up by the solid is 2/π2.
