Angles A and B are vertical angles.
If \(\displaystyle{m}\angle{A}={104}∘\) what is the \(m\angle B?\)

Answers (1)

Vertical angles are congruent. Therefore \(\displaystyle{m}\angle{A}={m}\angle{B}.\) If \(\displaystyle{m}\angle{A}={104}∘\), then \(\displaystyle{m}\angle{B}={104}∘{m}\angle{B}={104}∘.\)

Assum T:\( R_m\) to \(R_n\) is a matrix transformation with matrix A. Prove that if the columns of A are linearly independent, then T is one to one (i.e injective). (Hint: Remember that matrix transformations satisfy the linearity properties.
Linearity Properties:
If A is a matrix, v and w are vectors and c is a scalar then
\(A 0 = 0\)
\(A(cv) = cAv\)
\(A(v\ +\ w) = Av\ +\ Aw\)

Let \(\left\{v_{1},\ v_{2}, \dots,\ v_{n}\right\}\) be a basis for a vector space V. Prove that if a linear transformation \(\displaystyle{T}\ :\ {V}\rightarrow\ {V}\) satisfies \(\displaystyle{T}{\left({v}_{{{1}}}\right)}={0}\ \text{for}\ {i}={1},\ {2},\dot{{s}},\ {n},\) then T is the zero transformation.
Getting Started: To prove that T is the zero transformation, you need to show that \(\displaystyle{T}{\left({v}\right)}={0}\) for every vector v in V.
(i) Let v be an arbitrary vector in V such that \(\displaystyle{v}={c}_{{{1}}}\ {v}_{{{1}}}\ +\ {c}_{{{2}}}\ {v}_{{{2}}}\ +\ \dot{{s}}\ +\ {c}_{{{n}}}\ {v}_{{{n}}}.\)
(ii) Use the definition and properties of linear transformations to rewrite \(\displaystyle{T}\ {\left({v}\right)}\) as a linear combination of \(\displaystyle{T}\ {\left({v}_{{{1}}}\right)}\).
(iii) Use the fact that \(\displaystyle{T}\ {\left({v}_{{i}}\right)}={0}\) to conclude that \(\displaystyle{T}\ {\left({v}\right)}={0}\), making T the zero tranformation.
