1.9 The Matrix of a Linear Transformation Flashcards
1
Q
standard matrix for the linear transformation
A
let T: Rn –> Rm be a linear transformation, T(x)=Ax and A is the standard matrix
2
Q
onto
A
a mapping T is onto Rm if each b in Rm is the image of AT LEAST ONE x in Rn; linearly dependent (columns of A span Rm)
3
Q
one to one
A
if each b in Rm is the image of AT MOST ONE x in Rn; linearly independent
