## Hi Every \(\displaystyle \sum_{n=1}^{\infty} \dfrac{1}{n(n+1)}\)

Welcome back! Here comes the third edition, the April Newsletter. The name originally came from Aprilis, meaning 'to open'. In April, small animals that were hibernating usually come out and the birds fly back northward to settle, bees and butterflies begin to gather nectar. Also known as the Mathematics Awareness Month, what it boasts of the most, is it's first day, the April Fool's Day.

### New and Exciting Features

\(\bullet\) Over the month, Sir Lin has started a Party. Make sure you don't miss it.

\(\bullet\) Want a free Brilliant T-shirt? Get \(\displaystyle 10/10\) problems right in this set.

\(\bullet\) Have a go at all problems in the Troll King Contest. If you have already tried all problems, don't read this. If you already have, forget it.

### Challenging Problems

This month, if you were busy and couldn't muster time for Brilliant, no worries! You can have a go at the best of the problems which were posted over the month.

That's Plenty of Digits There, How Does This Relate to Pie, Practice Your Radicals!, Brilliant Games Quarter Quell 5, and Angle Bisectors were some of the easy problems which tricked Sharky and me.

Binary Operations, No Red Allowed, Trigonometric Series-Trinity, Crazy Inequalities-1, Just Subtract! Its easy! Isn't it?, and set Just a Little Twist are some of the tough challenging problems which were too hard for Robert.

### Special April Fools Section

\(\bullet\) As mentioned earlier, you can visit the Troll King Contest.

\(\bullet\) If you can prove that there exists a prime \(p \le 10^{100}\), that divides \(\displaystyle 103040!-1\), you must as well like to participate in the \(\displaystyle \mathfrak{JOMO}\) April Fools Contest.

\(\bullet\) If you're unsure of an answer to a problem, enter the answer in the box, and Press \(Ctrl+W\). This will not waste you a chance, and won't affect your ratings. Sorry, nothing available for MCQs.

### Some Other Random Stuff:

\(\bullet\) Brilliant just welcomed some new moderators, including the likes of Alan Enrique Ontiveros Salazar, Ritwick Choudhary, Sir Michael Mendrin, Sir Sharky, etc. Brilliant's gonna be more Brilliant with them as mods!

\(\bullet\) You can participate in the Open Proof Contest.

\(\bullet\) You might like to see this,this and this for some great motivation by Sir Sandeep.

\(\bullet\) We've met some great new members, who deserve great attention for their contributions. Here is the list of New and Active Members, in no particular order.Aryan Gaikwad, Bryan Lee Shi Yang, Akash Gupta, Aniket Verma, Andrei Golovanov, David Holcer, and Swapnil Das are the future Agni's.

### Who To Follow

Last, but the most important and awaited, here comes the \(\color{Blue}{WhoToFollow}\) list. A list of the top \(\displaystyle 7\) on Brilliant. They are a sure to be followed, if you want the best of Brilliant at your feeds. Here is the list, in no particular order:

\(\bullet\) Nihar Mahajan

\(\bullet\) Pranjal Jain

\(\bullet\) Sharky Kesa

With a special thanks to Sharky for helping me, we come at the end of the April Newsletter. Hope you liked it. You can send any feedback at \(\text{calvin@brilliant.org}\) LOL. Stay tuned for the May one; till then, good bye, and have a wonderful month ahead. Don't forget to troll whenever you can.

Cheers!

sir, i completed the set. do i get a free t-shirt, or is it just another april fools prank?

Log in to reply

The condition is to get 10 / 10, and not just "complete the set". Given that there are only 9 problems, you have been trolled (again).

Log in to reply

I believe its (obviously) a prank.

Are you trying to troll again, Mr. Golechha, with the Ctrl + W? People who know keyboard shortcuts know that that closes ALL your tabs.

Log in to reply

Yes, he is one of the big trollers. And btw, it closes single tab on Chrome.

Log in to reply

Oh, right, I was using Ctrl+Shift+W.

Try my set - Financing Risks. Anyone who gets 10/10 will get a free prize.

Log in to reply

If you can reshare it i will give a prize.HAHA nice one

Log in to reply

Actually it is a prank. My set only has 9 problems, so nobody gets 10/10. Everyone who has saw this note has been trolled. XD
