Here's a brainteaser for you, /sci/.

Prove this is true for all n > 2. If you can't do it, you must leave this board, for you are a brainlet and cannot be helped.

Can someone tell me what equations I can use to solve an exercise saying: "A man is pushing a cart of 100kg horizontally with the speed of 1m/s. If he changes the force of pushing by delta F=20N, then what will be the speed 3s after increasing the force?

I dont even know what to begin studying to solve this shit.

I NEED HELP WITH QUANTUM MECHANICS

>quantum mechanics midterm in two days
>prof is nice but explains like shit, literally writing entire blackboards at top speed and erasing the blackboard before asking if he can erase it. He doesn't upload explained solutions to his exercise sheets
>Forced to try to understand the exercises he's solving focusing completely on what is he doing OR copying them, losing track of what am I even writing and why.

So basically I understand the photoelectric effect and some operators, but I don't know how to solve monodimensional, bidimensional and tridimensional "particle in a box" problems. Is there any webpage that has solved exercises that could help me? I literally need a resource that holds my hand during the solving process and I'm sure I will be able to understand it after I analyze and repeat those solved examples.

How accurate is the Bureau of Labor Statistics?

No.10133920 ViewReplyOriginalReport
I compared the data for software devs, electrical engineers and mechanical engineers.

According to the BLS, there are about 1.25 million employed in software development, 325K in electrical engineering, and 289K in mechanical engineering. Their projected growth rate from 2016-2026 is 24%, 7%, and 9% respectively. Software devs also have the highest income.

Am I missing something here or is a Computer Science degree really worth a lot more than an EE or ME degree?

Here are the links:

Making an egg crate function.

I'd like to turn a 1D function into a form of 2D function.

Think of how in 2D a sine function looks like an egg carton. If you follow any line parallel to the x or y axis you get a sine function in z.

I need a function like that but for real(log(cot(x))).

Is Randomness actually possible?

No.10137687 ViewReplyOriginalReport
Please tell me if this paradoxon has a name yet.
(I will not adress things like Anti-matter or particles that pop in- and out of existence because I don't wanna)

So, per (wikipedia's) definition, something would be 'random' if it was done without thinking about it or with a deeper meaning behind it. But for the sake of my argument I'll be using it to describe something that has happened, will happen, or is going to happen in the future, without any way of even theoretically calculate or predict.

Here is what I've been thinking:
Nothing is random. Everything has been and still is the result of the direction, velocity and amount of stuff at the beginning of the Universe.
So if you had enough processing power and all the information of every single thing that has happened in the past you could calculate the future.

You can apply this logic to almost everything. If a human tries to make a random decision, his decision will only be the combination of all his and his ancestors' experiences, choices and thoughts up to and at that moment in his life.

I can see that this argument is lacking because it is currently impossible to actually get the information and processing power needed to calculate things like that right now, but in theory it still is possible.

So every movement, every decision, everything that has happened or will happen is predictable and has a reason. Right?
So how could something actually be random?
If everything could've been calculated since the beginning of our Universe, how can something be unpredictable?
And is there actually something that can't be calculated?
When you think about it, isn't Science entirely based around the fact that everything can be predicted and/or calculated?

Pic doesn't have a deeper meaning, I just wanted to put something there that remotely represents randomness.
