Define the sequence {b} by
bo = 0
Ել ։
= 2

bn=4bn-1-4bn-2 for n ≥ 2
(a) Give the first five terms of this sequence.
(b) Prove: For all n = N, bn = 2nn.
Let a Rsuch that a 1, and let nЄ N. We're going to derive a formula for
Σoa without needing to prove it by induction. Tip: it can be helpful to use C1+C2+...+Cn
notation instead of summation notation when working this out on scratch paper.
(a) Take a a² and manipulate it until it is in the form Σ.a.
i=0
(b) Using this, calculate the difference between a Σ0 a² and Σ0 a², simplifying away the
summation notation.
i=0
(c) Now that you know what (a – 1) Σ0 a² equals, divide both sides by a − 1 to derive the
formula for
a².
(d) (Optional, just for induction practice) Prove this formula using induction.
3.
Let A, B, and C be sets and let f: A B and g BC be functions. For
each of the following, draw arrow diagrams that illustrate the situation, and then prove the
proposition.
(a) If ƒ and g are injective, then go f is injective.
(b) If ƒ and g are surjective, then go f is surjective.
(c) If gof is injective then f is injective. Make sure your arrow diagram shows that 9 does
not need to be injective!
(d) If gof is surjective then g is surjective. Make sure your arrow diagram shows that f
does not need to be surjective!

Let X be a set and let f: XX be a function. We say that f is an involution if
fof idx and that f is idempotent if f f = f.
(a) If f is an involution, must it be invertible? Why or why not?2
(b) If f is idempotent, must it be invertible? Why or why not?
(c) If f is idempotent and x E range(f), prove that f(x) = x.
Prove that [log3 536] 5. You proof must be verifiable by someone who does not
have access to a scientific calculator or a logarithm table (you cannot use log3 536≈ 5.7).
Define the sequence {a} by a = 2-i for i≥ 1.
(a) Give the first five terms of the sequence.
(b) Prove that the sequence is increasing.

Suppose also that a market analysis shows that the buying habits of the customers fit the following pattern in the quarters that were analyzed: each quarter (three-month period), 30% of A users will switch to B, while the rest stay with A. Moreover, 40% of B users will switch to A in a given quarter, while the remaining B users will stay with B. Finally assume that this pattern does not vary from quarter to quarter. (a) If A initially has all of the customers, what are the market shares 2 quarters later? (b) If A initially has all of the customers, what are the market shares 20 quarters later? (c) If B initially has all of the customers, what are the market shares 2 quarters later? (d) If B initially has all of the customers, what are the market shares 20 quarters later?arrow_forward
- 1. The regular representation of a finite group G is a pair (Vreg, Dreg). Vreg is a vector space and Dreg is a homomorphism. (a) What is the dimension of Vreg? (b) Describe a basis for Vreg and give a formula for Dreg. Hence explain why the homo- morphism property is satisfied by Dreg. (c) Prove that the character ✗reg (g) defined by tr Dreg (g) is zero if g is not the identity element of the group. (d) A finite group of order 60 has five irreducible representations R1, R2, R3, R4, R5. R₁ is the trivial representation. R2, R3, R4 have dimensions (3,3,4) respectively. What is the dimension of R5? Explain how your solution is related to the decomposition of the regular representation as a direct sum of irreducible representations (You can assume without proof the properties of this decomposition which have been explained in class and in the lecture notes).
