 May14 awarded Caucus Apr26 comment Can I use my powers for good? @DanB I think that game development is important to society, since it has the potential to spill out benefits into other fields. See math.ucla.edu/~jteran Apr23 revised Stability of a matrix briefed it Apr23 suggested approved edit on Stability of a matrix Apr1 comment What's the relationship between singular, nontrivial and linear dependent? Basic linear algebra question. Here's an explanation of points 1-4 of the Invertible Matrix Theorem provided in the answer: 1. $A^{-1}$ exists. 2. $A$ can be obtained from the identity matrix, $I$ by a finite number of row operations. 3. All columns and rows of $A$ are linearly independent. 4. "For a linear map $f:A \to B$, the kernel of $f$ is the set of elements of $A$ that map to $0$ in $B$. The kernel is trivial if it contains only the single element $0$ (which must map to $0$ in $B$ by linearity)." - Henning Makholm chat.stackexchange.com/transcript/message/8765408#8765408 Apr1 suggested rejected edit on What's the relationship between singular, nontrivial and linear dependent?
