Given that u Tu and v Tv as well as u Av show that A Tt
Given that u\' = Tu and v\' = Tv as well as u = Av. show that A = T^t A\' T Notice that T is the transformation matrix with TT^t = I, u and v are vectors, and A are second rank tensor. Using only equations given here, nothing else.
Solution
To show TA=A\'T (as TtT = Id)
Apply both on v and show that they are equal.
TAv = Tu =u\'
A\'Tv= A\'v= u\'.
Hence the claim
