Abstract Algebra
Let n ≥ 2. Show that Sn is generated by each of the
following sets.
(a) S1 = {(1, 2), (1, 2, 3), (1, 2, 3, 4), ..., (1,
2, 3,..., n)}
(b) S2 = {(1, 2, 3, ..., n-1), (1, 2, 3, ..., n)}
1.Calculate the commutator C of Dn
2.Calculate the commutator C of Sn where n=3,4
(use the fact that if H is a normal subgroup of G, then
G/H is abelian if and only if C is contained or equal to
H)
(a) Find the limit of {(1/(n^(3/2)))-(3/n)+2} and use an
epsilon, N argument to show that this is indeed the correct
limit.
(b) Use an epsilon, N argument to show that {1/(n^(1/2))}
converges to 0.
(c) Let k be a positive integer. Use an epsilon, N argument to
show that {a/(n^(1/k))} converges to 0.
(d) Show that if {Xn} converges to x, then the sequence {Xn^3}
converges to x^3. This has to be an epsilon, N argument [Hint: Use
the difference...
Let sn = 21/n+ n sin(nπ/2), n ∈ N.
(a) List all subsequential limits of (sn).
(b) Give a formula for nk such that (snk) is an unbounded
increasing subsequence of (sn).
(c) Give a formula for nk such that (snk) is a convergent
subsequence of (sn).

1. 3 Sn2+(aq) + 2 Al(s)??2 Al3+(aq) + 3 Sn(s). What is the
voltage for this cell?
2. What is the Gibbs Free Energy for the above reaction assuming
standard conditions?
3. What is the Gibbs Free Energy for the cell in question 1 if
the Sn2+(aq) is [.15] and Al3+(aq) is [1.80]?
4. Describe what happens within the salt bridge between the two
cells
Let sn be a Cauchy sequence such that ∀n > 1, n ∈ N, ∃m >
1, m ∈ N such that |sn − m| = 1/3 (this says that every term of the
sequence is an integer plus or minus 1/3 ). Show that the sequence
sn is eventually constant, i.e. after a point all terms of the
sequence are the same
