Expert Solution
Step 1
Given :
To Determine : Eigenvalues and eigenvector geometrically .
Step 2
Consider a Point P(x ,y) =(x , y)
Hence T is reflection of point along x-axis
Now Consider point along x-axis (x , 0)
then
It is Fixed Points
Hence point in the x axis are considered as 1-eigen space and hence the 1 is an eigen value for T
Now Consider points on the y-axis (0 , y)
then T(0 , y)=(0 , -y)
Hence y-axis is an eigen space with -1 as the eigen value for T
Hence Eigen value is 1 and -1
Now , we find eigen vector corresponding eigen value 1
