Find the eigenvalues of a \(2\times 2\) matrix.
Find a basis for the eigenspace of a \(4\times 4\) matrix associated with a given eigenvalue.
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 quadratic polynomials (including complex ones).
-
Interpret the statement “\(A\) is an invertible matrix” in many equivalent ways in different contexts.
