Best ResponseYou've already chosen the best response.1since A is invertible, it can be broken up into the product of two matrices \(A=XY\) combine the properties \((AB)^T=B^TA^T\) and \((AB)^{1}=B^{1}A^{1}\)

Best ResponseYou've already chosen the best response.1This is what I wrote down, does this make sense haha \[CA^{T}=A^{T}C=I\] \[(A^{1})^{T}A^{T}=(A(A^{1}))^{T}=(AA^{1})^{T}=I^{T} = I\] and \[A^{T}(A^{1})^{T}=((A^{1})A)^{T}=(A^{1}A)^{T}= I^{T} = I\]
