Happy new year, everyone
What textbook did you get? Which subjects?
What do you mean i doesn't exist?
>>8573707
One book on exercises in upper-undergraduate analysis.
One book on general exercises of undergraduate maths, covering mostly all topics.
One book in maths history.
One book called "Treaty in Algebra".
All of them are extremely good, but I just took a glance at the analysis one.
>Nature of the series [math]\sum_{n=1}^{\infty} a_n[/math] where
>[eqn]a_n = \int_{1}^{1/n} \frac{cos^2(t)*Log(1+\sqrt[3]{t})}{\sqrt[3]{1+t} dt[/eqn]
Wew lad
I would like to have a balloon sinuplasty done. I have a 65% s-shaped deviated septum (bent out of shape because a homeless guy headbutted me as hard as he could 8 years ago and I couldn't afford to have a doctor look at my nose or make sure it would heal correctly). Because of this, my ostia are basically pinched almost completely shut, and my sinuses cannot drain at all.
It seems obvious that a balloon sinuplasty would benefit me, but every doctor I see refuses to consider it unless I have a head CT scan done beforehand to "confirm" that I would benefit. How many fucking confirmations do you need? My ostia are pinched shut due to my crooked septum. You said it yourself. How could you possibly need to know more?
I fail to understand the supposed necessity of the CT scan, and the doctor never explains. Instead they dodge the question and bolt out the door to deal with the next patient.
I'm not going to irradiate my brain with 44 mGy just to doubly confirm what is already known. I just want the balloon sinuplasty done. There is zero risk. I don't care if the worst thing that happens is I get no results and I've wasted my money.
If someone here knows or can find an ENT specialist anywhere in the United States who is open minded enough to do this without a CT scan, let them know I will pay 25k USD in cash as an incentive (the procedure is normally around 4k). I'll sign a lawsuit waiver and an NDA if that's what it takes for them to feel comfortable with this idea.
If they actually follow through and do the procedure, then I will also pay (You) a 5k USD finder's fee for finding that doctor for me.
This is not a joke. I have the money, and I've known for a long time that I want it done. If the only way I can get it is with a bribe then so be it.
I can be reached at [email protected]

right so just to summarize why this post may interest you, I'll pay $5,000 USD to anyone who can find me a willing doctor.
$5,000 USD.

Biological limbs will always be superior to non-biological ones.
Imagine you are a person with most of your body is artificial. Your legs and arms are robotic. Your plane has crashed in the mountains and you are part of the survivors. What do you do? Unless you can get to a power source, you have a count down until you just become a useless stump. Now, you may think that this is unlikely. But the assumption that we will always have access to power is an assumption of developed nations. Imagine you're in a nation at war. Power is either inconstent or non-existant. What are people to do with their fancy powered limbs and organs now?
In contrast, biological body parts are powered by readily available oxygen and food. No special equipment is required. I'd much rather have those in any kind of survival situation.

>Superiority is decided by some retarded faggot on /sci/ and his made up scenario
Wow really makes you think
>>8568412
>made up
You mean reality? Life isn't all sunshines. Having vital parts of your body rely on electrical power is a huge flaw.
>>8568417
Having no body parts in the first place is a huge flaw. It's not like people are cutting off their goddamn arm so they can have a robot arm—they have the robot arm because their natural one is gone. It's really a case of something vs nothing, and honestly, I'd rather have something. If people WERE cutting their limbs off just to get the robotic counterparts, then I'd understand where you're coming from.
If your life depended on whether or not your parents could pass college algebra, would you be dead or alive?
If my life depended on whether OP is not a faggot, I'd be dead countless times by now.

How long would this take to watch?

A long time
Nobody is going to watch all this shit to gain the info necessary to answer this question. Because who gives a fuck? At a certain point, the magnitude of a number is incomprehensible, so even if we gave the correct answer, nobody would be able to appreciate or understand it.

I literally do something like this almost every problem.
You found your mistake. That's a win.
>>8576931
I'm the same way. I've learned I simply have to take the time to check my results by going through the process and just looking for for reasonableness. I rarely post anything flawlessly when I haven't first checked.
I can only remember doing something like this once. I mean I make arithmetical errors, but my handwriting is good. Maybe you should write better, brainlet.
what is the most useful topic of higher mathematics (beyond vector calculus) in terms of application, and leading well to other topics.
>Calculus of Variations?
>Complex Analysis?
>PDEs?
>Fourier Analysis?
I ask because I want to pursue applied mathematics in grad school. meanwhile, I am doing a bachelors in mech engineering, so I want to do some self study.
What about computational courses? PDEs is more useful than most people think. Sure, you can look 'em up and solve them numerically, but being able to look at them determine behavior is useful. I think the key is probably just taking what interests you. More is better, generally speaking. Start studying for the math GRE subject test now. Comparably, it isn't bad, but speed is important.
Differential forms, calculus of manifolds.

Functional analysis
How do you self educate while making progress?
I am going through mathematical methods for physics and engieering by Riley et all and also engineering mathematics by kreyszig.
I am only doing every other question so that I don't take too long. The Riley book seems to have mostly "Show that..." questions, many of which rely on literally "one weird trick" or something I never would've considered. Kreyszig seems more mechanical and rote.
Is one of these books a waste of time?
>>8576709
>Is one of these books a waste of time?
No.
>>8576709
I don't know why you would be reading two books if they are for the same thing.
If you are doing it for the problems then don't bother and just do problem from online problem databases.
>How do you self educate while making progress?
By knowing what your goal is and then questioning if as you study you get closer to your goal.
>>8576715
You are fucking retarded, get out.
Brainlet here, is there a book like spivaks manifolds but for precal/early algebra/trig?
All the calc books just have intro chapters that skip over it?
What's the
>big guy
text for bringing yourself up to spivaks?
>>8576630
"Like" in what way?
What does it even mean to say "I want a high school textbook that's like this graduate textbook"?
>>8576630
What do you mean by that. Do you mean Spivak's calculus book? I don't really know any books for elementary algebra except for Lang's basic math and Gelfand's books. I recommend ignoring Spivak's calc book, instead learning calc non rigorously from Thompson's calculus made easy, or Stewart or Strang. Then learn some linear algebra from Hoffman and Kunze or Axler and some analysis from Rosenlicht. Now use Rudin and you can go on your way doing math.
>>8576637
Essentially a book laying out all of the theorems for trig, limits, etc. Idk if what I'm asking for exists, see brainlet status
Just think, every class you take, takes you closer to meeting the Grim Reaper. And you're paying for the privilege.
Enjoy your cram sessions educated anon.

i wonder what the peer reviews will say about this study
>>8576627
>>8576627
i think they will be very skeptical because highly educated people have better access to health care and thus their brain tumors are caught skewing the data
What math should I improve in if I want to be a pilot?

What the fuck is this shit? I've watched this cuck try to explain it over 5 times but still don't get it. How the fuck do you get 4 simultaneous days in 1 24 hour period if each """"""quadrant"""""" is part of a fucking sphere?
https://www.youtube.com/watch?v=Tn2UCqL5qyo
In 1884, meridian time personnel met in Washington to change Earth time. First words said was that only 1 day could be used on Earth to not change the 1 day bible. So they applied the 1 day and ignored the other 3 days. The bible time was wrong then and it proved wrong today. This a major lie has so much evil feed from it's wrong.

find a cube IRL
point a light at it
put it so the light normal is perpendicular to one face
rotate it on the axis perpendicular to the light source
notice how each face will have a sunrise / sunset in one rotation

Im curious what college professors and those in academia think about the electric universe theory?
anyone here take any classes and ask about this maybe?
