Activity 3: Matrices as linear transformations

Use the applet below to explore the effect of transformation defined by the matrix

Drag the sliders to change the values v_x and v_y.

What do you notice? What do you wonder? List any observations you see below.

False or True?

The matrix

is known as the scaling matrix. The scaling is uniform if and only if the scaling factors are equal (that is, v_x = v_y).

Tick all that apply
