Let T∈ L(V), and let p ∈ P(F) be a polynomial. Show that if p(λ)
is an eigenvalue of p(T), then λ is an eigenvalue of T. Under the
additional assumption that V is a complex vector space, and
conclude that {μ | λ an eigenvalue of p(T)} = {p(λ) | λan
eigenvalue of T}.
Let T: V →W be a linear transformation from V to W.
a) show that if T is injective and S is a linearly independent
set of vectors in V, then T(S) is linearly independent.
b) Show that if T is surjective and S spans V,then T(S) spans
W.

Let V and W be Banach spaces and suppose T : V → W is a linear
map. Suppose that for every f ∈ W∗ the corresponding linear map f ◦
T on V is in V ∗ . Prove that T is bounded.
Let V be a finite-dimensional vector space over C and T in L(V).
Prove that the set of zeros of the minimal polynomial of T is
exactly the same as the set of the eigenvalues of T.
1. Let V and W be vector spaces over R.
a) Show that if T: V → W and S : V → W are both linear
transformations, then the map S + T : V → W given by (S + T)(v) =
S(v) + T(v) is also a linear transformation.
b) Show that if R: V → W is a linear transformation and λ ∈ R,
then the map λR: V → W is given by (λR)(v) =...
Using the relationship for internal pressure πT = T
(∂P/∂T)V – P, show that for a gas that obeys a truncated
virial equation of state: Z = PVm/RT = 1 +
B(T)/Vm, the internal pressure may be approximated as
πT ≈ RT2(Vm)-2∙(ΔB/ΔT).
Estimate the internal pressure at 1.0 bar and also at 10.0 bar for
a hypothetical real gas at 275K given
that B(T) = -28.0 cm3⋅mol-1 at 250K and
-15.6 cm3⋅mol-1 at 300K for this gas.
Suppose V is finite-dimensional and S, T are operators on V .
Prove that ST is bijective if and only if S and T are both
bijective.
Note: Don’t forget that bijective maps are precisely those that
have an inverse!
suppose that T : V → V is a linear map on a finite-dimensional
vector space V such that dim range T = dim range T2. Show that V =
range T ⊕null T. (Hint: Show that null T = null T2, null T ∩ range
T = {0}, and apply the fundamental theorem of linear maps.)
Suppose V and V0 are finitely-generated vector spaces and T : V →
V0 is a linear transformation with ker(T) = {~ 0}. Is it possible
that dim(V ) > dim(V0)? If so, provide a specific example showing
this can occur. Otherwise, provide a general proof showing that we
must have dim(V ) ≤ dim(V0).
