some of you might have noticed that i have been asking for help for my calc 2 class over the past month or so and some have helped me out greatly. We just started a new chapter of calc2 and i come to find out that the book i was using doesn't include this material (second time taking class but different book). i would buy the book but its $100 i don't have and there are two weeks left in the class. If anyone knows of an online resource/reference or pdf file that covers calc2 that would be great.
