Your ﬁnal exam is likely to have problems that do not resemble these review
problems. You should also look at the review problems for the ﬁrst two exams.
(1) Find the largest interval [a, b] such that sin x3 cos xfor all xin [a, b]. Find the
area of the region bounded by y= sin x,y=3 cos xbetween x=aand x=b.
(2) A continuous function f(x) on the interval [1,10] has the properties R8
1f(x)dx = 14,
R10
4f(x)dx = 7, R10
1f(x)dx = 2. Find R8

(4) Find Zx2ex3+4 dx,Zsin xcos x dx,Ztan xsec2x dx.
(5) A bacterial population quadruples in size every 7 days. How many days does it take
for this population to triple in size?
(6) Explain why the function f(x) = n2x+ 1 if x1,
4x1 if x > 1is continuous but not diﬀeren-
tiable.
(7) A continuous function f(x) is deﬁned by f(x) = |x|ln |x|if x6= 0,
aif x= 0, where ais a
constant. Find a. Is f(x) a diﬀerentiable function? Find the intervals where f(x) is
increasing and the intervals where f(x) is decreasing. Hint: Look at the case x0 and
use symmetry.
(8) Let f(x) be deﬁned for x > 0 by f(x) = x2ln x. Find the intervals where f(x) is
concave up and the intervals where f(x) is concave down.
(9) Consider f(x) = x6
6x4
4. Find the local maxima, local minima and inﬂection points.
Find the intervals where f(x) is increasing, the intervals where it is decreasing, the intervals
where it is concave up and the intervals where it is concave down.
