yeah, and low iq

I am good at physics but suck at calculus. But this calculus is like a really difficult theory course and not your normal calculus. We do a lot of proofs. I don't know what you mean math but I figure if it was just computation calculus with no proofs then I would do well but as it stands down now I have a much higher mark in my other classes than calculus.

oh boy you're in for a treat

It actually characterizes the functions into certain groups or categories depending on whether you can find elementary antiderivatives for example. It's a very strong theoretical study, at first sight it's obviously dumb just like "straightedge-compass constructions" seems arbitrary and dumb until you use field theory to study it

>>7710383
>Why are these called closed forms: pi, e, sqrt(2), ln(3)
Closed form is a hazy definition to begin with in my experience. Generally it refers to elementary functions like Sin[x], Sqrt[x], Exp[x], Log[x] or constants like Pi. I can't tell you why such functions are considered elementary. For example, the error function has a relation to Exp[x] but it is considered special.

>Why aren't integrals called closed forms?
Not all integrals can be defined in terms of elementary functions or known special functions without creating new functions altogether.

>What's the point of finding closed forms of integrals or sums?
Because it is easier to describe integrals and sums in terms of what is known out there. Look at your pic OP. It's easier to describe the sum in terms of 3 constants (two Pis and an integer) than it is to wield around an infinite sum.

>>7711042
yeah, closed is sort of a social definition. functions or constructions are considered 'closed' when there is a concensus that they are easy to work with or considered familiar enough to us.

>>7710304
Shit-tier architecture class like the one I had.

Just use common sense desu, it's piss easy if you know your definitions.

>>7710304
Go to bed. Every second of studying you do at this point is actually negative value - the missed sleep hurts your performance than the studying helps.

>tfw got a B+ in architecture
By the grace of god. I don't even know how I pulled it off. I thought I was failing everything except the projects.

>>7710242

Stop thinking that it's hard, or that it doesn't make sense.

It's not necessarily simple, but it does make sense. You're just missing something. Keep trying.

Calculus is literally baby "calculate X". Just see it as a method to calculate something.

>>7710242
Calc. requires shittons of focus and modern technology definitely lessens one's ability to focus. Enjoy having the attention span of a goldfish.

>>7710225
I do it and it helps me. Otherwise I get depressed so yes you could try it. Don't overdo it and you will be fine

>>7710225
If you don't have a natural deficiency and you follow a good diet, then yes, it is a waste of money.

>vegan
>eat mostly pasta, onions, beans, potatoes, and bread
Yeah, get supplements. You are a faggot.

>>7710233
Agreed.
OP is a faggot

If wood warps what does it do?

>>7710221
What the fuck is a "war page"?

>>7710221
curvature is exactly what you think, except it is impossible to imagine in 3d.
I believe Warpage is when 2 very distant point in space can be connected with a short path through a worm hole.
the later is scifi bullshit.

>>7710047
Sure, I've seen them all probably anyway.

>>7710438
Man, I wanna watch yours.

Need more background info, things like past medical history, age, weight, ethnicity, comprehensive panel ect, it isn't easy with no blood tests, could be as simple as a vitamin deficiency with no blood tests.

>>7709835
Thanks for the response. I have had blood tests, no real issues there from what has been brought. I think I'm gonna get a new blood test from possible increased estrogen levels if you think that might be a problem, but there has no been real decrease in testosterone. I was still afraid that my vegetarian diet was causing this so I recently starting eating meet again but it didn't really make a different. When I first stopped eating meat I got a blood test and they told me I was the most healthy I have been. I thought my adderall prescription combined with marijuana use might have caused this (I saw anecdotal stories on the internet that might confirm this) so I stopped using both but I had no real difference. I've been taking multi-vitamins recently as well. I'm getting more blood tests done soon for the possible increased estrogen levels (which kind of seems unlikely) and for a unrelated stomach condition. I'm going back to my urologist soon, what should I talk to him about to get the best procedure possible (in terms of tests and variables in my lifestyle?) english isn't my first language so I apologize for issues in what i say

>>7709846
Also, Caucasian, (mostly irish ancestry) 163 lbs (usually underweight but am getting older so for my 6 foot height it's not as bad) and i'm 21. If you know what vitamins could affect this please let me know. sorry for my dumb responses by han solo your my only hope

It's happening. At long last, it's finally happening.

the exhaust gases push against the rocket

gas goes one direction, rocket goes in the opposite direction

>>7709765
The combustion of the fuel itself pushes the rocket away from the burning point. The engine does not push on anything, it is the push.

It's a force like magnetism; it can do work in the physics definition; thus, it is a force.

In layman's terms it's the attraction of matter to more matter; like how two magnets stick to each other, and how those two will gather more and more until there's a massive clump of magnets, and none in the immediate area.

Bad example, but it gets the point across. Swap magnets for any matter- gas, elements, molecules, rocks, planets... That's how you get atmospheres, solar systems, galaxies, and everything else down to the atomic level; that goes into things that I won't discuss here.

He asked about gravity itself, not relativity, quantum mechanics, or the origin of matter. 99% of your posts had nothing to do with the OP's simple question.

>>7709772, bugger off. He's not wrong entirely. There are some good points in here.

so on this note
why doesnt the milky way revolve around a huge black hole or something?

ok so are you saying that the faster something's velocity the slower it moves through time?

>>7709687
>milky way is travelling...

With respect to what exactly?

Bumping because I don't want my tongue to fall off in my sleep

>>7709603
>>7709624
Your tongue is fine.

Do you know how long the time was between it being frozen and you putting it in your mouth?

I wouldn't be scared.

Cryonics!='cryogenic sleep'

Cryonics is vitrifying people. This involves getting people injected with cryopreservant and getting them really really cold. These cryopreservants are toxic and the vitrification process causes cracks to form, so it is not currently reversible.

It's a stretch to call it sleep.

>>You would have spent thousands of dollars to give yourself the experience of waking up from death just to experience the pain of dying again. It would be the closest thing to hell possible in that one instant.

What makes you think it would be painful? And is it not worth it to extend your life even just a bit? Would you rather die in the next 60 seconds or pay $10,000 dollars and die in the next hour?

>>7709403
They will test with animals you dumb fucker.
