You are expected to work on this assignment prior to your tutorial during the week of
September 16th. You may ask questions about this assignment in that tutorial.
In your tutorial during the week of September 23re you will be asked to write a quiz
based on this assignment and/or related material from the lectures and textbook readings.
TEXTBOOK: Single Variable Calculus, Early Transcendentals, 7e, J.Stewart
READ: Stewart: Sections: 1.1, 1.2.
Notes: 1 Functions pages 8-14. .
Calculus Review Manual (CRM) pages 6-11.
A. Homework problems from the lectures:
1. Show that:
(i) the product of two even functions is an even function.
(ii) the product of two odd functions is an even function.
(iii) the product or an odd and an even function is an odd function.
2. Use the factor theorem to show that
4 3 2
(a) x − 2x + 4x − 5x − 6 is divisible by x − 2.
5 4 3 2 2
(b) x + 4x + 2x − 2x + x − 6 is divisible by x + 2x − 3.
(c) x + (2 − a)x + (5 − 2a)x − 5a is divisible by x − a.
3. Use the rational root theorem to ﬁnd if p(x) = x + 8x + 19x + 22x + 10 has any
rational roots. If there are such roots factor p(x) as far as possible. P(x) R(x)
4. For the following functions f(x) =D(x) express f(x) in the form f(x) = Q(x)+ D(x) ,
where the deg(R) < deg(D).
i) f(x) = x ii) f(x) = x + 1
x − 1 x − 2
iii) f(x) = x iv) f(x) = x − b
x − 2 x + a
v) f(x) = x − 3 vi) vi) f(x) = x − 1
x + x + 1 x + x + 1
