I am having trouble with the beginning of calculus, were using the book shown. I was wondering if there was anywhere online I could use to teach myself stuff quickly to get caught up.

>> No.1450148

do you have the solutions manual?
the book teaches you how to do it, other than that use youtube tutorials .

Concepts are not terribly difficult (Not trying to bust your balls).
Just do tons and tons of problems to familiarize yourself, then start thinking about the concepts.

>> No.1450163

try googling calculus on google books
there are hundreds of full view/open source books from prior to the 1920s

you should be able to find one that fits you

there are lots of modern calculus books that totally suck ass, and the one you are using may be one of those

basic limits?

the derivative of a function is the slope of the function at that point?

an integral is the sum of an infinite series of small rectangles?

what concepts are too difficult to grasp?

this is how i tackled basic finite limits:

just replace the variable with the limit being evaluated.

You don't have to be a maths major to do well in this class. The more practice problems you do, the more comfortable you will be with the subject.
Go to class, do problems based on the lecture.
It's okay to completely rely on your notes to finish problems at first.
Keep doing them until you don't need your notes or a book.
This is a class you can brute force your way through: just through the volume of work you do, you'll eventually get the concepts.

Limits are the hardest part of freshman calculus, but understanding them is important. It probably seems hard because it won't resemble any math you did in high school, but stick with it and keep working examples and it should start to make sense.

>> No.1450430

>>1450317
I realize summer classes are faced paced, but if you watch Kahn Academy or MIT lectures, you're still going to be watching an additional 3 hours of online lectures each day to catch up. That's a lot of time, and I think it would be more beneficial to spend it doing practice problems.
I've watched a ton of the MIT lectures- they're great. The concepts are explained clearly, and I feel like I've understood things fairly well. But it's a whole different world when you actually start doing practice problems.
Find people in your class to study with, or go to office hours if you can.

Explain to me how practicing calc problems would not benefit you.

Big intro classes are always hard. Doing practice problems could mean you get a 65 instead of a 27on an exam. D's are for diplomas, my friend.

Youtube's PatrickJMT (username) is pretty helpful.
I tried tutorvista for a month (say your in grade 12 and just doing advanced calculus, they live in india they won't know)

torrent the entire solution manual. learn to cheat on mathxl. study. think about things theoretically. proving things will make it sit in your finite little brain better.

do all of your work yourself. make sure you get 100% on all the homework even if you cheat, just make sure you study for the exam. scrape for every point you can get. there are about 3 limit scenarios, learn them! learn all your factoring in case you don't already. read and understand the syllabus. read ahead if you can. do extra problems. do all of the easy problems in the book. work on speed. speeeeed! finish problems as fast as you can. take adderal. do coke. easy A.

>> No.1450655

>>1450522

Everyone practices the problems. But the exams were very difficult and long; if you could finish all the problems you would beat 85% of the class. It pretty much came down to being an IQ test, without all the bawwing that would happen if they actually tested IQ and used it as part of admission into science majors.

and thats why im glad I started at a community college, there was about 20 people in my clac 1 class, and the teacher actually gave real homework that they graded. not some online, or voluntary bullshit.

the tests werent hard, but i got an A in the class, so maybe they were hard for other people, and everyone else was whining and telling the prof to slow down. I think reading way ahead is key in clac 1, and actually read it. read every single word and try to understand the proofs and do the examples.

>> No.1450806

I just realized something. I think it is better to just read the book and struggle with it, then to just find a more efficient learning method like videos or khanacademy or whatever.

because when you read the book and struggle, it forces you to test misconceptions, and explore your misunderstandings, and by doing that you get a better understanding of the subject. as they say: "an expert is someone who has made all the possible mistakes in a very narrow field" if you just have someone spoon feed it, then you wont have a real grasp, and you wont have any knowledge outside of what you have been spoon fed.

lol I did this too, took community college calculus, g chem and physics as a junior in high school, then o chem, biology and 3 more math classes as a senior.

Then when I showed up at my university I was at least 2 years younger than everyone else and had a 3.98 GPA (highest of anyone I met in my major) because I got to skip all the weeder classes. I actually had to stop telling people about this and started denying it and even told some people I was making it up because the butthurt was so deep and severe. Graduated 3rd in class out of 120 people in EE when I was 20 lol, and I'm really not all that smart.
