Let (V, ||·||) be a normed space, and W a dNormV,||·|| -closed vector subspace of V. (a) Prove that a function |||·||| : V /W → R≥0 can be consistently defined by ∀v ∈ V : |||v + W||| df= inf({||v + w|| : R≥0 | w ∈ W}). (b) Prove that |||·||| is a norm on V /W. (c) Prove that if (V, ||·||) is a Banach space, then so is (V /W, |||·|||)

Let U and V be vector spaces, and let L(V,U) be the set of all linear transformations from V to U. Let T_1 and T_2 be in L(V,U),v be in V, and x a real number. Define vector addition in L(V,U) by (T_1+T_2)(v)=T_1(v)+T_2(v) , and define scalar multiplication of linear maps as (xT)(v)=xT(v). Show that under these operations, L(V,U) is a vector space.
