>no argument

some brainlets says that
[math]\sqrt{-1}\sqrt{\frac{1}{-1}}\neq\frac{\sqrt{-1}}{\sqrt{-1}}[/math]
this is actually false
[math]1=(i)(-i)=\sqrt{-1}\sqrt{\frac{1}{-1}}=\frac{\sqrt{-1}}{\sqrt{-1}}[/math]
the issue here
[math]\sqrt{-1}\sqrt{-1}\neq\sqrt{-1}\sqrt{\frac{1}{-1}}[/math]
[math]i\cdot i\neq(i)(-i)[/math]

Generation ships with self-replicating probes dispatched in the millions in every direction. Doesn't matter if it takes hundreds, thousands, or millions of years. They will make contact eventually and Fermi will be BTFO. And if they don't make contact with other civilizations they'll still make contact with each other and, having been separated for millions of years, think they're making contact with non-human civilizations and Fermi will once again be BTFO. In every conceivable way, one civilization will make contact with another and Fermi will be BTFO.

>inb4 human-based lifeforms making contact with other human-based lifeforms doesn't count
Yes it does you fucking brainlet because you can't prove to me that we're not some spawn from some extraterrestrial civilization a la Prometheus.

The first part goes to 0 because [math]a_k=constant<0[/math]

The second part goes to 1 because is other way to write 0.99999999.....=1

Where do you gets i, brainlet

First off I'm not talking about the "smart but lazy" meme, I do attend and everything.
I'm actually good at understanding, visualizing, finding general properties and proving them, but whenever there's a test with long, drawn out questions I fail miserably (well, I don't fail but I barely pass).
It's not just in my head either, profs have noticed this and they always ask me what happened when I get poor grades. The truth is I don't know. I can explain stuff to others, and evidently I "see" it better than most (I have no reason to lie on the internet) but whenever I'm faced with a test with a specific function/series/sequence I'm stumped.
Should I just work more and focus on solving specific types of exercises? Anyone know that feel?

ChemE really is the best major.

Show me what you've got, brainlets.

>play old shows I watched before on my second monitor
>studying efficiency increases twofold

WTF?

What are the best subjects for semi-NEETs to study in summer?

Is there any scientifically-proven methods to increase IQ and become smarter?

Don't do the calculations.
Read the problem, go through the process of solving it in your head and skip it once you know you can solve it.
