Apologies to all of you who were eagerly waiting for their fortnightly links, I was feeling sick and didn't feel like writing this one. On the other hand, on March 18 this year I announced that I wanted to do something with Fano 3-folds, à la superficie.info, and in a few days I will release what I came up with.

# Alternate Angles
A transversal is a line that intersects with two or more other lines.
When transversals cut lines, they form many different pairs of angles. In this article, we're interested in alternate angles, which are sometimes also called alternate interior angles.
## Locating Alternate Angles

# Proof of $\lim\sup(a_nb_n)\leq \lim\sup(a_n)\limsup(b_n)$
Let $a_n>0$ and $b_n\geq 0$, then $\lim\sup(a_nb_n)\leq \lim\sup(a_n)\limsup(b_n)$
My attempt at a proof is as follows. Let $A_n=\sup\{a_n, a_{n+1},…\}$, $B_n=\sup\{b_n, b_{n+1},…\}$, and $C_n=\sup\{a_nb_n, a_{n+1}b_{n+1},…\}$.
Note: $a_mb_m \leq A_nB_n$ fo... | |

x+2y=6...(1)
2x+6y=8.....(2)
First let us multiply (1) with -2 and add to (2)
-2x-4y=-12
2x+6y=8
==> 2y=-4
==> y=-2
==> x= 6-2y = 6-2(-2)= 6+4=10

# Absolute value
In this section you'll learn how to the find the absolute value of integers.
4 - 0 = 4
4 - 1 = 3
4 - 2 = 2
4 - 3 = 1
4 - 4 = 0
4 - 5 = -1
In this pattern you can see that 4 - 5 is equal to a negative number. A negative number is a number that is less than zero (in this case -1). A negative number is... | |

# Should cosecant be defined as $\csc \theta = \frac{1}{\sin \theta}$, specifying the constraint: $\sin \theta \neq 0$?
I'm studying trigonometry on my own, and I keep noticing that the trigonometric functions are never defined with constraints to deal with divide-by-zero issues. As an example, I've seen cosecant defi... | |
