Before beginning this chapter, you should be able to...

1. Calculate the area of a parallelogram.

2. Recall and use the definition of a linear transformation

3. Find the matrix corresponding to a linear transformation of Euclidean spaces

4. Find all roots of quadratic polynomials (including complex ones).

5. Interpret the statement “$$A$$ is an invertible matrix” in many equivalent ways in different contexts.
