Expert Solution
Step 1

Note : " As per our guidelines we will solve three subparts . If you want any specific subpart to be solved please specify that subpart or post only that subpart . "

(.)  Linear map  T : 2 2   given by ,

                 T(x,y) =  (y,x)

(.)  Standard basis of  2  is   (1,0) , (0,1) .

(.)  Let  T: V(F)  V(F) be a linear transformation  , then  λF is a eigen value of T if and only if  T-λI is singular . Here  I is an identity transformation and  V is a vector space over the field  F .

(.)  Singular linear transformation : A linear transformation  T is said to be singular if there exists a vector  u0 such that T(u) = 0 .
