Guided Proof Let ${v}_{1},{v}_{2},....{V}_{n}$ be a basis for a vector space V.

Prove that if a linear transformation$T:V\to V$ satisfies

$T({v}_{i})=0\text{}for\text{}i=1,2,...,n,$ then T is the zero transformation.

To prove that T is the zero transformation, you need to show that$T(v)=0$ for every vector v in V.

(i) Let v be the arbitrary vector in V such that$v={c}_{1}{v}_{1}+{c}_{2}{v}_{2}+\cdots +{c}_{n}{V}_{n}$

(ii) Use the definition and properties of linear transformations to rewrite T(v) as a linear combination of$T({v}_{j})$ .

(iii) Use the fact that$T({v}_{j})=0$

to conclude that$T(v)=0,$ making T the zero transformation.
