Question
Another Shear Transformation The matrix for a shear transformation of 2 units in the $x$-direction is$$\mathbf{M}=\left[\begin{array}{ll}1 & 2 \\0 & 1\end{array}\right]$$Apply the transformation matrix $\mathbf{M}$ to the matrix shown in Table 5.1.2 for the r-shape in Fig. 5.1.6. Graph the transformed $\mathrm{r}$-shape.

In $R^{3}$ the shear in the $x y$ -direction by a factor $k$ is the matrix transformation that moves each point $(x, y, z)$ parallel to the $x y$ -plane to the new position $(x+k z, y+k z, z) .$ (See the accompanying figure.) (a) Find the standard matrix for the shear in the $x y$ -direction by a factor $k$ (b) How would you define the shear in the $x z$ -direction by a factor $k$ and the shear in the $y z$ -direction by a factor $k ?$ What are the standard matrices for these matrix transformations?
