Ok. So I have a huge problem with Trigonometry. I don't understand it at all. The problem I believe I'm having is that I can't set up the equation properly. I have a TI 30XIIS calculator if that helps at all.

Need help in Calc2. What do I have to do in order to determine the height of a shell? Everything else makes sense to me, I'm just confused as to how I'm supposed to know 1-y^2 is the height.

How scientifically accurate is the processes it shows of make meth on the show?

This might be the most retarded thing you have ever read, and I have a shit way of explaining things. But the big bang, if it was just a star going supernova. Everything just appeared out of fucking nowhere and space is expanding, so I'm short I think we live in a black hole. We don't know what's inside of black holes but what if they are different universes getting created. Terrible explanation I know.

>Consider the following: Instance: A bipartite graph G = (L, R, E), k \in \mathbb{N}. Question: Is there a set L' \subset L of size at most k such that for every v \in R, there exists a u \in L' where vu \in E? How do I prove that this problem is NP-complete?

hello I have been given this and told it contains a coded message by a superior. am I missing something or is it complete bullshit?

Can someone help me with Fourier Transforms? I'm in a graduate level MSE class as an undergrad (senior) ChemE for a minor, and I'm the only ChemE. The professor was assuming we have seen these already and I haven't. Anyways, that equation for J is what I'm trying to solve. I can do it analytically or numerically, according to the problem statement. I know I have to perform a Fourier transform to do it by hand. I also know the convolution theorem is useful, as we were given the fourier transform for the gaussian function that composes the two pieces of the integral. But if I take the fourier transform of both sides, how can I eventually solve for J? Wouldn't J be in fourier space? Thanks ahead of time :/

Yo help me out with this problum, i think its the 3rd one C but im a little unsure. Which statement best explains the energy transformation that occurs when methane burns (CH4 + 2 O2 ? CO2 + 2 H2O)? Which statement best explains the energy transformation that occurs when methane burns (CH4 + 2 O2 ? CO2 + 2 H2O)? The absorption of heat results in an increase in potential energy from reactants to products. A decrease in entropy from reactants to products is released as heat. A decrease in potential energy from reactants to products is released as heat. An increase in entropy from reactants to products is released as heat.

So i'm reviewing some limits of sequences and shit and came upon this bad boy (pic related). Now, I'm not the smartest when it comes to remembering these rules but I assume that I am to employ L'Hopitals rule and shit. When doing this, do I take the product rule of the numerator? I'm fucking confused as shit. Could be from the lack of sleep tho >inb4 wolfram Already tried there but they didn't explain shit cause algorithms and shit

Can anyone give me a chemical reaction with three reactants?

I have a question : You can travel through time? (Of course i'm not the real John Titor)

Time dilation is overrated. {T^{\alpha \beta }}_{,\beta } = 0\ Why does no one ever talk about the generalized conservation law in special relativity? It is possibly one of the most amazing equations in all of science, seeing as how it describes the behavior of just about anything (as long as you ignore gravity).

how would someone bind an electron to a nucleus?

/Sci/ why am I afraid to study? Was it because I was praised for my slightly above normal intelligence as a child and subconsciously acquired the belief that studying is for chumps?" I've got textbooks next to me, a list of things to do, and I'm literally afraid to start and keep putting it of. Any help?

Is there any connection between earth's magnetic field and electrons inside the human brain?

I want to master in plant biology and environmental science, are there any interesting readings I could have on those subjects ?

What would happened if I just turned the entirity of my attention and spare time to learning maths? Give this example, say I'm a 20 yr old taking first year calculus, (and some other sciences for that fact). This class is so slow, that if I took all of my spare time, I could probably know up to Calc 3s before the end of the semester. Now, what if this time was extended over a longer period? By the time I'm taking grad school maths, I would have taught myself the knowledge of phd level maths, and would be able to challenge theories, have stronger thesises etc tl;dr, can you actually make yourself some kind of math jesus? ---- If you autisticly put all of your spare time into maths (Which I probably wont do since i like having sex and experiencing life), would you be able to turn out a significant result by your old age? This is given someone of a moderate deviation of intelligence (Take me for example, 125-129 verified) I'm thinking someone like Feynman,

I've never taken stats before. It's taking me hours to get through a 6 question assignment. It has stuff like P(A|B) and P(A U B) and shit like that. It seems to be a lot like physics. You have to find the correct formula for each problem, but it takes me too long. If I stay at this pace I will not do well in the course. What should I do sci? This course is taking up half of my study time and I have 4 other courses. I have taken other 200 level math courses and I don't remember them being this time consuming.

I have an answer, but does anyone know where I would submit it? "The observer(i) exists within the field (lim(i>5)={(cos(?)*sin(?)*cos(?),sin(?)|i<?<c2, i<?<c2}=10) whereby {e[K°/t2]=(m2/c)*(m-m/c)/4}."

Any ideas?
