Question
Use
the following theorem:
If T:Rn → Rm is a linear transformation, and e₁,e2, ..., en are the standard basis vectors for Rn, then the standard matrix for T
is
[T] = [T(e₁) T(e₂)
T(en)]
Find the standard matrix for T:R² → R² from the images of the standard basis vectors.
T:R² → R² reflects a vector about the line y = x and then reflects that vector about the x -axis.
