The *point* "**.**" is a mathematical abstraction. It has negligible size and a great sense of position. Consequently, it is front and center in abstract existential reasoning.

**A** = ((a_{ij})) is a **translation matrix** of order 3.

a_{ii} = 1 for all *i*s; a_{12} = 0; a_{13} = x_{0};

a_{21} = 0; a_{23} = y_{0};

a_{31} = 0; a_{32} = 0.

Determine **det A**. What values of x_{0} and y_{0} will cause

every point on the plane to be a *fixed point* under the translation represented by **A**.

**A** = ((a_{ij})) is an **orthogonal matrix** of order 2.

if a_{11} = 3/5; a_{12} = 4/5; a_{21} = -4/5; a_{22} = 3/5;

Determine the **transpose** and **inverse** of **A**

and whether **A** is **proper** or **improper**.

**A** = ((a_{ij})) and **B** = ((b_{ij})) are matrices

representing **projections of the plane**.

a_{11} = 1; a_{12} = 0; a_{21} = 0; a_{22} = 0;

b_{11} = 1; b_{12} = 0; a_{21} = 1; a_{22} = 0.

Test for the **nonsingularity** of the transformations.

The point P(1,1) is projected under **A**, the result is then

projected under **B** to the point P^{'}.

Determine the coordinates of P^{'}.

**A** = ((a_{ij})), is the matrix

representing a *a shear parallel to the x-axis*.

a_{11} = 1; a_{12} = k; a_{21} = m; a_{22} = n.
**A** maps the vertices of a rectangle onto the vertices of a parallelogram as follows:

(0,0) -> (0,0); (2,0) -> (2,0);

(2,1) -> (5,1); (0,1) -> (3,1).

Determine the values k, m and n.

**A** = ((a_{ij})), is a scalar transformation matrix of order 2.

a_{11} = k; a_{22} = 1/4.

Determine if **A** represents a *uniform stretching* of the plane or a *uniform compression* of the plane.

What change should be made in **A** inorder for it to represent a *dilation of the plane*.

What is the difference between a transformation matrix representing a *dilation of the plane*

and the transformation matrix representing a *magnification of the plane*.

The Linear Transformations T_{1} and T_{2} are reflections of the plane.

T_{1} is the case where the points on the x-axis are fixed points.

T_{2} is the case where the points on the y-axis are fixed points.

Determine the reflection matrix of:

(a)T_{1} (b)T_{2}

((A_{ij})) and ((B_{ij})) are reflection matrices of reflections of the plane.

A_{11} = 0; A_{12} = 1; A_{21} = 1; A_{22}= 0

B_{11} = 0; B_{12} = -1; B_{21} = -1; B_{22}= 0

Determine: (a) The *mirror* associated with ((A_{ij}))

(b) The *mirror* associated with ((B_{ij}))

What is the determinant of the rotation matrix of the following transformation:
**T**(x, y) = (xcosθ - ysinθ, xsinθ + ycosθ).

What is the matrix of the transformation:

**T**(x, y) = (-x, -y)?

Identitfy the *rigid motions* that correspond to the following transformations:

(a) **T**(x, y) = (x+7, y-7).

(b) **T**_{1}**T**_{2}(x, y).

Where **T**_{1}(x, y) = (x, -y) and **T**_{2}(x, y) = (y, -x).

(c) **T**(x, y) = (xcosθ - ysinθ, xsinθ + ycosθ).

Abigail asked Abel to work on the transformation **T**(x, y) = (x^{2}, xy). Abel computed **T** and told Abigail he is not interested in T because it corresponds to a *non-rigid motion*. What is a *non-rigid motion*? Is Abel right? Describe the * non-rigidity* of **T**.

**T** is an identity transformation. Vector **u** = (x, y). What is **T**(**u**)?

**T** is a one-to-one linear transformation from the m-dimensional linear space X into the n-dimensional linear space Y. What is the value of m if n^{2} = 9?
