my solution is in that link
http://img246.imageshack.us/my.php?image=img8267rf4kq1.jpg
i solved it using that method
i want to transform a matrix from a standart basis to basis B
A-out old matrix
X- the old basis
Y-the new basis
S-the transformation matrix
S^-1 -its inverse
N-resolt
i did
Y|X>>>I|S
S|I=I|S^-1
N=S*A*S^-1
the problem is with the solution that i was given
but the problem is that the solution that i was given is totaly different

A-old matrix
B-new basis
N-answer
i noticed that he takes
B|A>>> I|N
thats totaly different i can't see any logic in that
and he got a different answer from me
and he got full points for that
that gives me a great dought in my method
can you please tell were am i wrong??
