Question

a linear transformation y= Ax is said to be orthogonal if A is​

Answer 1

Answer:

In general, a linear map T is defined to be orthogonal if T preserves inner products. To be more specific, if T is a function from a vector space V to itself, T is defined to be orthogonal if ⟨v,w⟩=⟨Tv,Tw⟩ for every v and w in V.
