Hi guys, started a new topic in university.

We are currently doing different stuff with matrix calculation, but in this case I dont know how to combine each matrix with one another.

Assignment:

I have the bases and

of a 3-dimensional ℝ- vector space V, with:

I need to find out and .

What am I supposed to do? I know that it has something to do with the change of the basis and I understand that you can get the same result if you approach this from two different ways, "similar to homomorphism".

What am I supposed to calculate with and in which way?
