    Quick plz! T(A) = Tr(A)

    1. The problem statement, all variables and given/known data
    Let T : M22 define as T(A) = Tr(A). Show that T is a linear transformation
    and find the dimension of ker T.

    2. Relevant equations

    3. The attempt at a solution

    what is Tr(A)?
    is it trace(A), or rT(A) , r is a real number?

    It's most likely the trace.
