Analysis and Calculus

I have to take calc soon. I am not good in math at all. The farthest I've been is Algebra II and some Trig. I'm nervous!

hey guys, like i've said before i really don't like math..well i do when i understand it. when something goes right it feels the same as when i program i write works. but this is crazy HOW DID IT DO THIS??? im bad with simplifying radicals, really bad. thanks for any help. btw i understand that cos²x+sin²x = 1 i dont see how it was split, the way im looking at ti looks wierd. how can i hust take a t out of (t + ***)² its not the same as (t(****))², it needs to be expanded right? :confused:

and its EASY! im teaching myself from the book because the prof. sucks! i like this better than other types of math...i dont know why... ill probably be posting in here a lot throught the semester EDIT: by semester i mean 4 weeks...summer classes compress 16 weeks to 4

Okay, I am in the middle of learning single variable calculus and I can understand most of the topics I've learned so far. There are some things that are not obvious or easy understand to me, e.g. the Fundamental Theorem of Calculus: int(a,b, f(x) dx) = F(b) - F(a) , where F is an antiderivative of f. I can understand that in order to find the area between two intervals one would subtract the smaller area from the larger. So I guess this would imply that taking the antiderivative of a function and evaluating it at some point (we'll call it b) would give you the area from 0 to b. (Someone verify this) I see computing the area under a curve from the development o…
