Transformation of a Unit Square

The video tutorial explains how to transform a unit square using a transformation matrix. It presents two methods: calculating matrix products for each vertex and using column vectors of the transformation matrix. The first method involves more computation, while the second is more efficient. Both methods yield the same result, transforming the square into a quadrilateral with parallel opposite sides, known as a shear transformation.

What is the primary goal of the transformation discussed in the video?

• To increase the size of the unit square

• To rotate the unit square by 90 degrees

• To draw the image of the unit square under a transformation matrix

• To change the color of the unit square
