Hey /sci/.

I'm having some difficulties with calculus and physics. Can I get some recommendations for some self learnimg sites? My textbooks are utter shit, and classes are very... intuitive.

Oh, and don't say Khan academy. It's only good for basics.

Calculus is advanced math, you guys are probably just elitists who think only advanced topology analysis counts and anything else is babys

What the fuck are you talking about, children in the Orient learn calculus before they are 10 years old. Advanced math my ass. Seems like someone is trying to rationalize their mathematical incompetance.

>> No.3822181

Calc is basic math.

If you don't find it intuitive, you are likely to have problems down the road with higher-level math courses.

Oriental children have high IQ's. Seems like someone is trying to make themselves feel smart by putting down other people.

come on OP, you can't really think calculus is advanced math.

>> No.3822216

>>3822181
I don't disagree. I already understand the whole concept of it, differential, integral, the whatnot. It's the insanely long problems and intuitive derivative rules (I'm looking at you, chain rule).

Oh, and I'm following the AP physics c:mech course for those of you wondering. I'm just fucking lost with vectors, free body diagrams, and equilibrium stuff.

if you don't understand how intuitive is used you have no hope of understanding basic math like calculus. Just give up.

>> No.3822343

>>3822314

but the way he's using it he should be saying intuitive. Why would you complain about a textbook or math problem being intuitive?

>> No.3822365

Maybe its easy in class, but later when hes doing (or probably not doing) homework its not so much anymore.

With math, you just have to do all the homework and not get behind. Seriously, do all the homework.

>> No.3822371

>>3822343
A lesson being intuitive would be good and bad. You could comprehend it, but not logically understand the logic and proofs behind the subject.

A textbook should be intuitive, on the other hand. This is because interfaces, papers, and websites use a different meaning of the word. For example, you could call youtube intuitive.

>> No.3822393

>>3822371
Intuition, as it applies to math, is the notion that you understand why a method works.

If you don't know the method, you can't know why it works. You might have intuition on what a derivative IS, but you need intuition on your rules of differentiation.

Just for perspective, there's a "business math" class where they teach business students whose last class was college algebra those derivative rules. There's a reason your non-applied math class spent several weeks exposing you thoroughly to the differentiation equation, it's so you can understand why these rules work now, as opposed to just having them as handy shortcuts.

If you don't know it, run the equation through the differentiation equation and see why the derivative rules work for it. Chain rule is easy and khan academy does explain it very thoroughly

The best way to learn calculus is to learn it properly.....When i did calculus in high school, I didn't truly understand it, but I learned much more in university where my professor teaches it as rigorously as possible. Definitions and proofs are the only real way to know if you understand why something works.

Recommend Stewart's calculus book.

Get Calculus A complete course, by Adams, Essex. I think it's a brilliant book together with the student solutions manual. I'm from swedish and my english isnt that great but still I have no problem with this book, must mean its pretty good.

>> No.3822745

>>3822551

I'll double up on that Stewart recommendation. Really appreciate how well laid out that book is once you get into more rigorous mathematics.

>> No.3823053

I'm studying Calc III atm.

Stewart's textbook is pretty good, I think.
(calculus, early transcendentals, 6th edition)

>> No.3823110

Are the earlier versions of Stewart's Calculus much different? I was thinking of picking one up to re-learn calculus and an older version is under $2 on Amazon.

No, I just think that anyone who hasn't got calculus down before attending university must be quite the dunce.
