Introduction
Readiness Assurance.
Before beginning this chapter, you should be able to...
-
Calculate the area of a parallelogram.
-
Recall and use the definition of a linear transformation.
-
Find the matrix corresponding to a linear transformation of Euclidean spaces.
-
Find all roots of a quadratic polynomial (including complex ones).
-
Interpret the statement “
\(A\) is an invertible matrix” in many equivalent ways in different contexts.
