I have a question regarding the computation of a hyperplane equation (especially the orthogonal) given n points, where n>3. For lower dimensional cases, t...

I'm noob in math. If 0.333(3) is 1/3, 0.666(6) is 2/3, then 0.999(9) is what? If 3/3 and 0.999(9) is the same, then how can I express one of them wit...

Here is a simple question: Why does it not make sense to define addition on points in geometry? To be a bit more specific: assume we are talking only abou...

This is a lot simpler of a problem than others posted here, but I was bored in class and decided to work out why a horizontal asymptote exists. Bear in mi...

I've heard of some other paradoxes involving sets (i.e., "the set of all sets that do not contain themselves") and I understand how paradox...

I would like to show that $$\delta(\sin{x})=\sum_{n=-\infty}^{\infty}\delta(x-n\pi),$$ where $\delta(x)$ satisfies the relation $$\int_{-\infty}^{\infty} ...

On Wikipedia, the terms Exponential Growth and Geometric Growth are listed as synonymous, and defined as when the growth rate of the value of a mathematic...

This question might have even been asked here before, I don't really know, so sorry if it's duplicate. I've started to study topological sp...

Rotation in 2D by an angle $t$ can be performed using $$R=\begin{pmatrix}\cos(t) &-\sin(t) \\ \sin(t) & \cos(t)\end{pmatrix}$$ matrix. But, if I w...

Is there any software that lets one explore group theory, ring theory, and category theory visually and theoretically that is tailored for education purpo...
