Here the distance is enlarged or compressed in a particular direction with reference to only one of the axis and the other axis is kept constant. We will use the properties of determinants outlined above to find det ( A). The range of the transformation may be the same as the domain, and when that happens, the Was Galileo expecting to see so many stars? Now notice that $\MVects nV$ is necessarily a one-dimensional space, corresponding to the fact that $V$ has one $n$-dimensional subspace (itself). Clone Hero Customs. First, observe that T\left (\begin {bmatrix}u_1\\u_2\end {bmatrix}\right )=\begin {bmatrix}u_1+u_2\\3u_1+3u_2\end {bmatrix}=(u_1+u_2)\begin {bmatrix}1\\3\end {bmatrix} So, the image of any vector of \RR ^2 under T lies on the line determined is linear.
