WebJan 26, 2024 · Calculate T ( 0 n) using step 1 and the definition of linear transformation. I will give three proofs. Proof 1. Since 0 n = 0 n + 0 n, we have T ( 0 n) = T ( 0 n + 0 n) = T ( 0 n) + T ( 0 n), where the second equality follows since T is a linear transformation. Subtracting T ( 0 n) from both sides of the equality, we obtain 0 m = T ( 0 n). WebFeb 27, 2024 · Proof Extension to .
