Am i an idiot or is my friend an idiot ?

To apply the transform T to a vector written in the standard basis you normally have to do three things:

>Rewrite the vector into base B
>Apply the T to the rewritten vector
>Transform the result back into base E

Those three operations can all be done with one matrix multiplication each so the composition of those three operations is just applying the product of those matrices.

Yes that's what i meant by [T]_B*[e_i]_B ,i will convert e_i to the coordinates in base B then multiply it with the matrix [T]_B and ill have the i'th vector of the representation matrix of T with relative to base E.
is this what you also meant?

Use LaTeX you dumbfuck.

My baboon mind cant comprehend how LaTeX works

i'm given [math][T]_B[/math] and need to find [math][T]_E[/math] ,so [math][T]_E=([T]_B[e_1]_B,...,[T]_B[e_n]_B)[/math] ,where for each [math][T]_B[e_i]_B [/math] is a column vector.

Thank you i thought ill have to go and use a compiler some where else !
