Worksheet: Linear Transformation Definition

In this worksheet, we will practice defining a linear transformation and stating whether a given transformation is linear.

Q1:

Consider the linear transformations for which v, the image of 10, and w, the image of 01, are unit vectors. Let 𝐿 be a linear transformation of this kind which has the additional property that the area of the parallelogram with vertices 0, v, w, and vw+ is as big as possible. What are the possible values of the measure of the angle between v and w for the transformation 𝐿?
