so whats the answer

The inverse only exists if the determinant is different from 0
Check this
If it exist A^-1/ A A^-1 = A^-1 A = I, (where I is the identity matrix) then det (AA^-1) = det A det A^-1 = det I = 1.
So, if det A = 0 there is not an A^-1 so that 0 det A^-1 = 1

Well....... It certainly does appear that it's singular.
No, the inverse isn't 0. The inverse doesn't exist.
And aren't you glad they didn't give you a 4 X 4 matrix âº
