# Math Help - matrix representation of linear algebra

1. ## matrix representation of linear algebra

I am stuck trying to figure out how to solve for a matrix A given the transformation T(v) and v.

I have T(v) = Av and need to find A (a 2x2 matrix). Any ideas?

post the question. if this is the kind of question i think you are asking, you just need to reverse matrix multiplication. which is easier than it sounds, since the numbers tend to be in their respective positions

3. ## The question

Ok so I have v = [.3355, .4792]^t and T(v) = [-.1747, .8478]^t and I am trying to find A (a 2x2 matrix), where T(v) = Av.
