Calc 101: Is it Worth Buying a Password?

[City88]

Hi everyone...
I was wondering if anyone had subscribed to calc101.com? Most of the site is free, but for step-by-step integration, you need to buy a password. But is it worth it? I'm taking an ad-cal course at the moment, and I would like to be able to double check various integration.
Thanks!

Yeah I tried it last year...the steps are not that clear and i didn't quite get which rules were used, to me it definitely didn't worth the money...

I don't think it would be worth it. There is too many free websites out there with many examples on almost all levels of calculus. I recommended:

http://tutorial.math.lamar.edu/

It's called Paul's Online notes and he provides complete solutions to all the examples he does on the website. I used it when I went through those calculus courses to supplement the material I learned in class and in my textbook. Look through the courses and you'll find a gazillion integration problems, integration methods, and the steps for the most common integrals. I found this site via google. Chances are if you are stuck on a problem in a first year calculus course, someone else has had the same problem and there is a solution somewhere out there online. Check out google!

paul's online math notes are pretty good for early calc classes, I also suggest them.
