I have to learn Calc 1 in a month via self-study. I have about 4 hours a day to do this. Any tips on a self-study approach? My current plan is working out of a textbook I have and watching 10-20 khan academy videos (and doing the exercises) a day. Tips very appreciated

How many volts would it take to A) Kill a person and B) Completely incapacitate a person It's for an experiment.

hey /sci/. 7th semester computer science gratuate student here. i like computer science, but i can't help but feel that the math stuff we learn in high school is so much fun than what i'm learning now. i'd say i like math very much, but not all kinds of math. i like calculus, combinatorial analysis, differential equations, recurrence relations, mathematical induction, set theory, linear algebra, etc. i like a plurality of topics more strongly connected with computer science too, like functional programming, first and second order logic, mathematical modelling in optimization theory, computability theory, etc. my understanding is that, the more specific the field, the lesser my interest in that field is. i feel like general subjects give me the possibility to play with them and their universes a lot more than specific subjects, that fundamentally just show me the facts and that's it. i'm taking courses in cuncurrent programming, fault-tolerance, compilers and history of computing, and i have never liked a semester less. compilers is cool, but not sufficiently cool to compensate for the other courses, which are, at the most, "kinda cool" so, am i crazy or something? someone shares my problem?

How do I prove that {(1 + \frac{x}{n})}^n converges to e^x? I cannot into series.

I don't get how I can reduce something to the halting problem to show it is not decidable. For example; How can I show that the problem of deciding if a turing machine halts on some input of length 4 is undecidable? I realise I need to reduce this to the halting problem to reach a contradiction but no idea how to do so formally...

If an 18 year old wanted to refresh his knowledge of Algebra, sufficiently learn Trig, Pre Cal, and enough calculus (for medical school), could this 18 year old do it in approximately 980 hours?

Is it proper to use a number as a variable?

I'm reading up on Organic Chemistry 101 and I understand the concept of chiral centres, but apparently citronella (pic related) has one and I cannot understand which carbon atom it would be. I immediately rule out any with a double bond, right? So that leaves maybe the 3rd carbon along? But it's joined to a methyl group, a hydrogen, and two CH2 groups... This isn't a homework question, I obviously already have the answer, but could /sci/ explain what I'm missing here?

what would be the ramifications if SETI found a regular complex non random signal?

What computer does /sci use? I'm saving for a MacBook Pro, I'm starting college in August.

When talking about variation, in something like: y ? x y ? x^n y ? 1/x y ? 1/x^n y ? ?x y ? 1/?x How do you work out changes to y if x is altered, say for example, x is doubled or x is reduced by thirty percent? Would you sub in values or is there a proper method to calculating percentage change for variation?

Fact: The Sahara Desert is caused by the Nile River. Discuss.

Does water have stored energy? Could I heat up a boiler full of water with electricity and expect to produce more energy than what was consumed to heat it? What if the water was pressurized before I began to heat it?

two questions how much force or weight can a the strongest tow cable available take before snapping? what is the standard output of a rocket thruster, even a weaker one?

To the mech eng and comp sci student on omegle who couldn't solve this problem. No, I don't hate you guys, you made an effort at least. Seriously though you two need to study harder. Also, you should really have been able to solve this.

Where does the (-1) come from?

Hi /sci/. Wondering If I could get a little help with an econometrics question, The question is related to CLRM in matrix form. Given a model represented by : y = XB + (Epsilon). Let B^ = OLS estimater for the model and e = vector f residuals. ie e = y - xB^ Prove that each element e(i) in e is a consistent estimator for epsilon. I gather it has something to do with plim but I have absolutely no idea. Also remember this is in matrix form and not standard form. ( i sometimes get confused by the differences in notation). Thanks

Hi /sci/, I want to learn Calculus. Which book should I use to start with ?
