Definition of a Limit
: If the values of f(x) can be made as close as we like L by taking values of
x sufficiently close to a ( but not = a) then we write limx->af(x) = L which is read The limit of f(x)
as x approaches a is L
Limits fail for the following

On March 28th two great men and mathematicians came to the University of North
Carolina in Asheville and debated the significance of pi versus that of e. These men fought long
and arduous debates proving their points on

Section 5.2, part I: The Definite Integral, a Definition
Let's make precise all of the whatnot we've been doing with areas, with a Definition. Let f be a function defined on the interval [a, b] and div
MATH 191, Sections 1 and 3 Calculus I Fall 2007
Section 5.1: Areas!
Today we'll work on perhaps the funnest topic of the semester. We all know how to find the area of nice rectilinear figures like squares and triangles, right? What if we're asked to

Section 4.9: Antiderivatives!
For numerous reasons that will become evident next semester when you take Calc II, the ability to work backwards, obtaining a function by starting with its derivative, is

Section 4.7: Optimizin' !
Remember the Closed Interval Method, that means we developed for finding the extreme values of a given function on a closed interval? Well, how about we apply that method (and

Section 4.5: Sketchin' !
With the help of calculus, we've now got several tools that'll help us understand the nature of the graph of a function f (x). Let's summarize our findings in an 8-step process

Section 4.3: Derivatives and the shape of things
We've already seen ways in which we can tell stuff about f by examining its derivative f . For instance, if f (x) = 0 everywhere on an interval, then f

Section 4.2: The Mean Value Theorem
Today's focus is probably the second (maybe third) most important theorem from all of calculus. (Only the Intermediate Value Theorem, which we mentioned when we defi

Section 3.9 Related Rates of Change
In applications, one frequently deals with problems in which more than one quantity is changing with respect to change in yet another. Even if some of the rates of c

The astute observer may have noticed that with all we've done with derivatives, we still don't know how to differentiate logarithms. It's about time we
