I'm going to agree with you. The leaves will grow in the direction of the closest star or artificial light, and the roots will grow in all directions. Without any light, obviously the plant dies.

The leaves will grow towards light - which is phototropism. But the roots grow towards gravity, geotropism. Flies have a similar gene and move away from gravity. Your answer is good, but I wonder where the roots will tend to grow.

I'll try to solve cubes in my head. by that i'll have to think through every move and advance my abilities.
i'll probably start with a 2x2x2. a standard cube seems to be fuckhard for such business.

But I'd like to know why this is so? If you could explain to a HS math plebian

That's what I thought cause if you over load on hat then you have worse odds in case you pick that hat.
Well, actually, no matter what it's the same odds because overall you have a 50/50 chance of picking either hat

>>5366609
That was so simple

Wolfram is telling me to put it in terms of e, too.
But I don't get how taking the natural log of a limit would make it into e form.

>>5347270
Oh, that makes complete sense now.
Can you help me with >>5347168?

>>5347234
No, the limit is definitely infinity.

If anyone kind enough does come along, maybe they can help me with this question, too.

lim (2x^2 +1)e^-x
x->infinity

>>5347177
kind**

>>5347168
no kinda anons?

I have a calc final tomorrow, and I'm studying and have no idea how to solve the following problem.

lim (1-2x)^(1/x)
x->0

Yeah, this is just simple circle angle rules. Mathematics 101.

Of course, it could be that more wealth = more wellbeing while more free time =/= more wellbeing. But it could easily be the other way around. This is an empirical question.

>>5345754
Thanks, that's a pretty good list. But I feel like I'll be squandering my academic ability if I do something like farming or bartending. So going to med school would be nice, but that would take about 8 years of hard work. That is not negligible.

So I suppose being a day trader is the only option left besides computer science. I do like economics, but I don't like money (hence the working 20 hours thing). So I'm not really sure...

>>5345634
>work a maximum of 20hours a week

The good life. And programming seems like the best way to do that that I know of. Perhaps you could be a consultant with any degree that's useful to industry, but you need years of experience working regularl 9 to 5, so that's out.

>>5345616
C'mon, you've got to admit that people over-value money to at least some extent. Look at jewelry. People will pay thousands of dollars to buy a real diamond as opposed to cubic zirconia, when it takes an expert with equipment simply to detect a difference. It's all about status.

>find something you're passionate about

The problem is I'm passionate about a lot of things. Math, physics, computers, economics, game theory, philosophy... Not to mention things you can't get paid for, like watching good movies, reading good books, listening to good music, philosophy...

And even if I could pick just one and make that my thing, who knows what I'll be passionate about in 10 or 40 years. That's why I'd like to have as much free time as possible. Use society's technological advantages to reduce the amount of work I have to do as opposed to increasing the amount of stuff, as I explained above.

Yeah really! It should be more normal. I am not an engineering student (economics and math) but I have gotten trained on machine tools, welders and I know a lot about soldering and electronics.

I meet a lot of engineers at my university who look down on machining, or soldering or whatever. Like, thats some plebian thing?

Thats REALLY bad. All the good engineers are good actually constructing as well as engineering. In a sense the practical skill must preceed the engineering, because actually being physically involved with it gives you insight into what can be feasibly engineered, and what cant.

Good thinking OP, I would do it if I only was somewhat quicker at using TeX.

Bump for greatness

I know nothing about binomial coefficients. I was thinking about integration by parts but none of my ideas worked out so far.
