Eigenvalues and eigenvectors are probably my favourite thing about this year. Although stuff like definingwas also pretty interesting. Even if my exam board does use j and not i

So it's not exactly interesting, more a joke a Maths teacher told me once.
sin x
n = 6
It's so bad it's good xD took me a while at first hehe -

wait wait wait wait wait. you do that in maths, but that's so scientific, how dare mathematicians cross the line of scientific knowledge.

Operator methods for solving differential equations - simple yet so elegant - avoids having to assume solutions for 2nd order.

No I didn't, I don't do maths- we did that in Physics. I took the thread title as topic area instead of subject (perfectly valid), So that was the most interesting maths I did in Physics and hecne most interesting thing in maths. -

Possibly complex integration - particularly using complex integrals to solve difficult real integrals, using the residue theorem, etc.

I just learnt Sylow's theorem part 1 (wish me luck for parts 2 & 3). That is a really nice piece of mathematics. It took me ages as well cause I had to learn group actions and orbit-stabiliser theorem before I could see how the proof worked.

The Wason selection task.
You are shown a set of four cards placed on a table, each of which has a number on one side and a colored patch on the other side. The visible faces of the cards show 3, 8, red and brown. Which card(s) must you turn over in order to test the truth of the proposition that if a card shows an even number on one face, then its opposite face is red?
I initially thought the answer was obvious but it turned out my initial intuitive reasoning was flawed.
Spoiler:ShowThe correct response is to turn over the 8 and the brown card.
Explanation- If the 3 card is red (or brown), that doesn't violate the rule. The rule makes no claims about odd numbers.
- If the 8 card is brown, it violates the rule.
- If the red card is odd (or even), that doesn't violate the rule. The red color is not exclusive to even numbers.
- If the brown card is even, it violates the rule.
