"NettetOne-to-one is the same as onto for square matrices We observed in the previous example that a square matrix has a pivot in every row if and only if it has a pivot in every column. Therefore, a matrix transformation T from R n to itself is one-to-one if and only if it is onto: in this case, the two notions are equivalent. " - Linear algebra one to one and onto

Nettet17. sep. 2024 · Therefore T is linear. T is one to one: We need to show that if T(→x) = →0 for a vector →x ∈ R2, then it follows that →x = →0. Let →x = [x y]. T([x y]) = [x + y x − y] = [0 0] This provides a system of equations given by x + y = 0 x − y = 0 You can verify that the solution to this system if x = y = 0.
