Exercise 1:

null space of Linear Transformation

Shaded portion is

Exercise 2:

rangeT of Linear Transformation

Shaded portion in domain is

Shaded portion in co-domain is

Exercise 3:

Consider the linear transformation T: R2R2 defined by

T(x, y) = (x, 2x); x, yR2

  • Null Space ≡ N(T) = {(0, y) : y }
  • range space
  • Nullity T =

  • Range ≡ R(T) = {(x, ) : xR}

  • Rank T =

  • range space

    Exercise 4:

    What will be the rank of the matrix of T w.r.t. the standard bases?
