Hello all,(adsbygoogle = window.adsbygoogle || []).push({});

I am re-teaching myself calculus (I don't remember anything from Calculus in college, and I only took calc I in college)

I am using the book stated in the title. I got up to page 65...so far so good.

Until it started asking me to compute definite integrals. Nowhere so far has it told me HOW to do so...it just explained the intuition behind it (fairly simple to grasp) and then starts giving questions...without telling me how to answer them! So I decided to just google how to do it, assuming maybe I missed something somehow even though I read it over multiple times....but all of the things I looked up when I googled, had not been introduced in the book yet!

So far in this book, there has been no mention of 1) What a derivative is 2) What an antiderivative is 3) what the central theorem of calculus is 4) how to integrate a function

So far, all I have learned about is some basic physics equations (f=ma, p=mv, w=fd, etc), the concept of an infinitesimal, the concept of a differentiation, and the concept of an integral...so far I understand all of these

So I skipped ahead a few pages thinking maybe I can just go back to it later, but the book just keeps going on talking about things that it has not explained. I am getting extremely discouraged and frustrated.

The only other book I have is Calculus by Spivak, and I think my girlfriend has the stewart book, but the stewart book seems to be mostly questions, and needs a teacher to guide, and I am self-studying so this does not help me.

Will I be able to work through Spivak with absolutely no prior knowledge of calculus (I know basic algebra and basic trig and some geometry)? Also, what levels of calculus does Spivak cover (in terms of calc 1-3 taught in school)? I am looking at Spivak table of contents and I don't see taylor series, chain rule, etc (I have no idea what these things mean, but I know I see them in other books)

What book should I be reading so that I know what the heck is going on? I want to 1) be able to compute the questions in the book (doesn't seem too much to ask) 2) Actually understand the concepts and understand why the formulas are the way they are. So far I was understanding everything in my current book until this, and now I am so lost and confused.

Thanks in advance for all of the help.
