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 |

If $f(y)=ax^2+bx+c$, does this imply that $x=\frac{-b \pm \sqrt{b^2-4a[c-f(y)]}}{2a}$? I was skeptical because usually the quadratic formula is used for constants. I didn't know it could be used for variables, but I suspected that it would work for variables because variables are just 'varying constants' in the sense that we can build a graph of infinite relations between $x$ and $y$ by using the equation infinite times. |

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 |

$\lim_{n \to \infty} \frac{\ln x^q}{x^p}$ not necessarily =0 for any $p>0$ and $q>0$ right? changed n to x |

Can $|-x^2| < 1 $ imply that $-1<x<1$? Lol, I get it. I just missed the step $|-x^2|=|x^2|$ |
