I need this book Calculus by James Stewart 8th edition.
Here it is, available from Amazon.
It can be found on amazon, or online if you know where to look, second hand is also an option.
I do not see the book as being rigourous though? I have here and I think there are better books.
You can also buy a cheaper older edition for under 5 dollars. Just take a picture of a classmates problem sets or go to the library and do it.
That is a statement. Do you have a question?
The question is very easily inferred. The Amazon suggestion is a good suggestion. Also, going to a public library's book sale, depending on what is typical at that site, may well turn up just what you are asking for, or other possible great finds.
I guess so, by why doesn't the OP answer?
He did not exactly ASK a question. He declared what he wants or "needs".
