1. The periodic function f(x) has period 2. It is defined in the interval 0≤x≤ by
f(x)=4x²
(a) Sketch this function on the interval -4л≤x≤4л for the two cases
i. f(x) is an odd function.

In this question work to 4 decimal places throughout and give your final answer to 3 decimal
places.
(a) Use 4 iterations of the power method to calculate an estimate of the maximal mag-
nitude eigenvalue of A and an estimate of the corresponding eigenvector. Start with
(1,1,1) as the initial estimate of the eigenvector.
Given that the the inverse of matrix A is

(b) Use this matrix to perform 3 iterations of the power method to calculate an estimate of
the minimal magnitude eigenvalue of A and an estimate of the corresponding
eigenvector. Start with (1,1,1)" as the initial estimate of the eigenvector.
