Can someone find why the following series converges?

[math]\sum_{k=1} ^{\infty} \left( e^{\frac{1}{k} } -1 - \frac{1}{k} \right) [/math]

[math]e^x=1+x+o(x^2)\quad (x\to 0)[/math]

[math]\implies a_k=e^{\frac{1}{k}}-1-\frac{1}{k}=o(\frac{1}{k^2})\quad (k\to \infty)[/math]

Because [math]\sum\frac{1}{k^2}[/math] converges, [math]\sum a_k[/math] converges.

Small error, it should be

[math]e^x=1+x+x^2+o(x^2)\quad (x\to 0)[/math]

[math]\implies a_k=e^{\frac{1}{k}}-1-\frac{1}{k}=\frac{1}{k^2} + o(\frac{1}{k^2})\quad (k\to \infty)[/math]

Because [math]\sum\frac{1}{k^2}[/math] converges, [math]\sum a_k[/math] converges.

Sorry.

Non-Biology guy here, but I've been wondering about this. Obviously the premise is silly since Stan just wanted an easy way for characters to get powers, but it's worth asking. Could, at some point in time, "mutants" like them exist? Granted, stuff like Storm, Proteus, Cyclops and whatnot are nigh impossible, but Angel, Wolverine, Ugly John, Marrow, they are possible.

Or, could we "create" them? Maybe with "Nanomachines, son"? I mean, at a certain point in the future and all, maybe someone like Fantomex could exist.

Dunno, but out of whatever nature the motivation for this will be, it's gonna be military for sure

Stop shit posting.

1/0. Nothing simply cannot Exist

----1x. There exists above, below, left, right, forward, back, inverse, exverse and all combination of these root directions

------sub_5. Motion is Observation vs Direction

2. There was always time in existence (undefined location)

---2x. Time is not antecedent of it's self (there was always 1+2)

------sub_6. Time is antecedent and subsequent, the eternal spiral (sub_5)

3. Measurement is the distance between time and two undefined locations (distance is time)

---3x. All location are defined through the measurement of time

------sub_7. Duality, the mutual incentive for being both infinite and finite

4. Observation is derived from the defining of locations 4=x

Why is there something rather than nothing?

Because nothing is a contradiction

In Australia, what is a viable sci career to should pursue for a high IQ person like me?

Would love to get a comfy 6 figure salary, after a few years in the career

If you're actually smart and capable data-analytics or any equivalent (usually a part of CS) is what you're looking for. Of course any field that makes money is hated on /sci/.

Bump i'm also curious.

Currently in 2nd year of 4 year physics and math degree at monash uni

Is there a list of books that covers pretty much the High School curriculumn

of Mathematics that is compiled in a user friendly way in some website;

from all the way from Pre-Algebra? (I'm planning on going to Uni to study Math)

I'm asking because I was that ADHD kid that would muck around in class

and not listen to the Teacher. :\

I was in the same boat as you. Anyway, I used Khan academy to catch up on math before going back to college.

Anyone have other cheat/reference sheets than this one?

I have some that cover every formula about one particular subject, but none that cover all of undergrad physics for example.

Not a request thread, just a thread to dump cheat sheets to help each other.

its all relative bruh

I prefer SPECIAL relativity. I don't see why I should share my relativism with the brainlets of the general population.
