Can someone tell me why Sum from j=1 to 3 of y_j*(x'_j , x'_k) = (f , x_k) for 1<=k<=3 where (x1,x2) is the scalar product integral, Would look like a matrix which is the transpose of what I would think it would look like? What I'm saying is, that I feel like it should be the transpose of what it is. Anyone understand my logic? P.S. I realize it's a symmetric matrix but I want to the know specifically why I'm failing to see it as the transpose of my inclination. Also, as you can see, the tex doesnt appear to be working; or I just don't know how to work it.
