Buy the basics (for me as a med fag: anatomy, physiology...) and rent those who are useful only to pass your exams.

I only buy books with 100% refund return policies. I take pictures of every single page of the book and return the book.

Yes if it wasn't so fucking expensive and time consuming currently.

Let's try it when we get better technology.

Not any time soon. It's a distractive ruse like the journey to Mars. Our day to day is a tangled mess of complexity and neglect. We've bought into Silicon Valley's rhetoric parroted by intellectuals making twitter clones. Outer space is really about tripping neurotransmitters like a bunch of junkies who can't deal with reality. Simulation much? Human civilization are the bearers of cavemen tech propped up almost exclusively on exploiting hydrocarbon reserves, and subsequently, all other natural resources.

People who talk about asteroid mining have no clue how mining happens on Earth.

no, it varies a lot.

>>8437908
how so?

it decreases when the sun sets, for one

Would you mind teaching it to us now? I can at least visualize rectangles, what am I and the rest of us brainlets supposed to think when doing a Lebesgue integral?

>>8437856
spoiler: if the domain of integration is unbounded then there are riemann integrable functions which are not lebesgue integrable.

>>8438101
correct me if I'm wrong, but isn't it rather the Kurzweil-Henstock integral ?

>>8437663
Since this is a multiple choice question, you can just test each one to see whether it satisfies the recurrence.

Also (2^m)^2 is 2^{2m}, not 2^{m^2}

And your second equation should be

T(2^{m-1})=T(2^{m-2})+2^(2*(m-1))

>Since this is a multiple choice question, you can just test each one to see whether it satisfies the recurrence.
True... but I actually want to learn something

hmm, how would I simplify, 2^m + 2^(2m - 2) + 2^(2m-4) . . . + 2^(0 - 2) ? Im not very good at maths. Would it be:

2^2m + 2^(2m -2) + 2^(2m-4) . . . .
factoring out 2^2m
2^2m(1 + 2^-2 + 2^-4 + 2^- 8 . . . (Idk what the last 2^(m-1)th term would be)

2^2m(1 + harmonic series??)

? lost idk how to get 4/3(n^2 - 1)

>>8437711
Yeah that's the right idea.
To figure out the last term, test a simple case like m=1. In this case, T(2^1)=T(1)+2^2.
Similarly, for m=2, T(2^2)=T(2)+2^{4}=T(1)+2^4+2^2. So your sum should stop at 2^2, not 2^(-2). And to get the answer just remember that n=2^m.

Alot of boomer-ish cucks don't comprehend numerical methods. It looks like witchcraft to them. It scares them because they know you can do what would be a year's worth of work for them in like a day. They know they're obsolete, but don't want to admit it.

Just be as patient as you can with them. You'll be in their shoes some day, and you'll probably be a grouch about it too.

I have a hard time dreaming up what I could have trouble with that the kids of tomorrow will understand. Maybe there will be a paradigm shift and they will give up on jobs and not understand why I make stuff and don't come live in the woods and eat squirrels.

You think wrong. You're not math retarded. You're actually just plain retarded.

You literally just write the definitions down and let the autistic connections in your brain do the work.

I'm guessing you're talking about epsilon delta proofs if you're in calc 1, and you don't really need to worry all that much about them, desu.

The material can be presented in a way that goes above your average calc 1 students ability, but all you need to do is memorize the the format. Work on replicating it over and over until you can do it by memory then try to focus on actually understanding it.

Any other proof presented in the book arent necessarily meant for you to understand (and indeed, a lot of the proofs of calc 1 material can't be understood with such a rudimentary knowledge of the subject), they're just showing you a basic idea of why you're doing it that way.
