1. The problem statement, all variables and given/known data
To determine the pseudoinverse of this matrix.
1 1
2 2

2. Relevant equations
I find it difficult writing out the equation properly so i have attached it as a doc file.
3. The attempt at a solution
I have taken the limit as $$\delta$$ tends to zero, but getting the inverse of the matrix is impossible. I need to use this to find the pseudoinverse. Thank you
