    A linear mapping T : R2 -> R3 is defined on the standard basis vectors via
    T(e1) = (1, 0, 1) and T(e2) = (1, 0, -1)

    1. Calculate T(3,3)

    2. Find the dimension of the range of T and the dimension of the kernel of T.

    3. Find the matrix representation of T relative to the standard bases in R2, R3.

    4. Find bases {v1, v2} for R2 and {w1, w2, w3} for R3 with respect to which T has diagonal matrix representation.

    A linear mapping T : R2 -> R3 is defined on the standard basis vectors via
    T(e1) = (1, 0, 1) and T(e2) = (1, 0, -1)

    1. calculate T(3,3)
    Since T is linear, then T(3e1+3e2)=3T(e1)+3T(e2), therefore
    T(3,3)=T(3e1+3e2)=3T(e1)+3T(e2)= 3(1, 0, ...
