Thread: A question of writing the vector u + 3 e2 in both basis e and f (Has a solution) img

Hello, i would like you to see my uploaded image, after reading it with the solutions you can see what I mean.

I would like to add, that the person who has done the solution has got Xe = (0,1,0) I would like to know how he got those values, thats all.

Thanks for uploading it, Im just waiting for someone who perhaps can answer how to get Xe = (0,1,0)
