In this part of section 6.5, we focus on work.
Denition. If a body moves a distance d in the direction of an applied constant
force F, the work, W, done is
W = Fcl.
Example 1. Find the amount of work done

magnitude and direction. We denote the vector v by a bold lower case letter,
in when we are typing. When w

7.3: Trigonometric Methods (Part 1)
This section is one of the biggest in Calculus 2, so we must take care to work
as many problems as we can. There are two main parts to this section. The
first part gives us a process to

7.7: Improper Integrals
In this section we discuss the two types of improper integrals. Improper integrals
of the first type are integrals where one, if not both, of the limits of integration
are infinite values. We are m

Definition. A sequence cfw_an is a function whose domain is the set of nonnegative integers and whose range is a subset of the real numbers. The
functional values a1 , a2 , a3 , are called the te

Section 8.8: Taylor and Maclaurin Series
The ultimate goal of this section is to find polynomial approximations of
non-polynomial functions.
Definition. The nth -degree polynomial function of f at x = 0 is called
the nth -degree

the coefficients of the series.
