It's fine just keep practice, stuff like that will become usual

I just went back to the book right now and wasn't even able to prove that the sum of the nth roots of unity was equal to 0. I looked at the answer online and it's just some 1 line (w^n - 1)/(w-1) =0 thing. I never would have thought of that.

REEE

Screw this, I don't have the motivation to self study maths.

Is it possible to become retarded after not using your brain for a while? I have done nothing since the beginning of 2014. Half of that in university, the other half outside of it. I got great grades at school but stupidly did a shitty engineering degree at a shitty university.

are you one of those fags who saves their popular posts for later use? we've read it once, we don't want to read the exact same thing again

Ya, infuriating, I know.

There's always a reason for that. They're helping you see a relation or something, rather than just telling you the proof.

you just have to stick with it for a while, and eventually you'll remember a bunch of standard tricks and get a feel for when to use them

Seeing is not perceiving

I always remember the trick but I still jave to Google it. Am I a brainlet?

Seriously, fuck this shit.

>>8625596
Feel like a brainlet right now with exponential function and generally geometry

it's not only possible but unavoidable

end it

So does that translate to, "would you like fries with that?"
