Help with text book mathematical notation

[jaredogden]

Okay so let's say (hypothetically of course) I am on my third attempt at the final Calc course in the series at my college.

I feel like my foundation of even simple mathematics and arithmetic is unstable to say the least for me. I enjoy the concepts of math and what it could be used for but many times I find myself with an incredible headache trying to figure out things such as notation used in textbooks and proofs of certain concepts that fly over my head like satellites. Are there any good resources out there to help me first of all figure out the last few concepts of multivariable calculus like line integrals and flux? Also after I finish this course I would like to try and use the time I have off to almost re-learn most of the math I have learned up until now. By re-learn I mean grab hold of every concept and understand how it works like why the heck we use pi to calculate area, circumfrence, and volume of circles, spheres, cylinders, and the like. So I guess that would be also be the theory of math..

So I said all that to say this. If there are any good resources out there like khanacademy that could help with this please post. Thanks ahead of time.

Khan academy is good. So is Wikipedia for most things. Often it helps to study the same thing from different sources. Sometimes the right combination of words finally comes together and it "clicks".

Yea, if you don't unerstand one way look some where else. Also try not to ask questions that are too 'deep' because it can be come too philosophical.
