Read on page #7 of article here, that angle of $90^o$ can be trisected. I went through this youtube video here, and here; and denote these two videos (den...

In most cases, I can intuitively understand when selection order is important in probabilistic inference. However, I've come across a few cases recen...

I am working on a past Algebra exam paper and have come across a problem which requires me to write the linear operator associated to a given matrix $M$ i...

I came across a proof that did the following. $a$, $b$, $c$ are $3 \times 1$ vectors. $A$ is a $3 \times 3$ matrix and $d$ is a $3 \times 1$ vector $\begi...

I have a little question regarding the error function that disturbs me a lot: Let us consider the classical error function defined as: erf($z$) $= \frac{2...

The equation is $$\frac{1}{5} - \frac{3}{x},$$ rewritten as $$\frac{1}{5} - 3x^{-1}.$$ So the anti-derivative should be $$\frac{1}{5}x - 3\frac{x^0}{0} + ...

I'm not seeing where the eigenvectors are in terms of eigenvalues in the paper that came out recently named "Eigenvectors from Eigenvalues" by the ne...

Why is the $y$ centroid of a semicircle and that of a semicircular arc different? Using Pappus' second theorem on a semicircle of radius $r$, $\bar{y...

I am slightly stuck and was hoping someone could clarify about the superposition of solutions to linear, non-homogeneous differential equations. I was tau...

From what I understand α |= β means that if α comes out true, so does β. ie, α entails β. This got me thinking, I know that there are truth tables for α →...
