How to show a transformation is linear
WebShow that the transformation T defined by T ( x 1, x 2) = ( x 1 2 − 2 x 2, x 1 + 5 x 2) is not linear. I know that the definition of a linear transformation involves: T ( u + v) = T ( u) + T ( v) for all u, v in the domain of T. T ( c ∗ u) = c ∗ T ( u) for all scalars c … WebDec 5, 2016 · My proof is as follows: Since f is linear, we know that there's some k ∈ R such that f ( x) ≤ k x for every x ∈ R n, in that case let a ∈ R n and let ε > 0. Consider δ = ε / k and suppose x − a < δ, in that case we have: f ( x) − f ( a) = f ( x − a) ≤ k x − a < k ε k = ε

Prove that A is injective iff { v ∈ V: A v = 0 } = { 0 } I read that a linear transform is injective iff the kernel of the function is 0, but I am supposed to use the fact that for all a, b ∈ V, A ( a + b) = A ( a) + A ( b).
WebNov 25, 2024 · In the case of x → x + d x; x + y → x + y + d x + d y = ( x + d x) + ( y + d y) so this transformation is linear. Does it matter if the transformation is not linear? It's super important: Most engineering and physics analysis depends on linearity. Non linear analysis is a field of study by itself.
