胖胖好像沒上這個版喔...
感覺上了大學以後就沒有他的消息了阿....
--------------------------------------
traditionally,that protion of calculus concerned with finding
tangent lines and rates of change is called differential calculus and that
portion concered with finding area is called integral calculus. however, we
will see in this chapter that the two problems are so closely related that the
distinction between differential and integral calculus is often hard to discern.
in this chapter we will begin with an overview of the problem of finding areas-
we will discuss what the term "area"means ,and we will outline two approaches
to defining and calculating areas. following this overview,we will discuss
the "fundamental theorem of calculus,"which is the theorem that relates the
problems of finding tangent lines and areas, and we will discuss techniques
for calculating areas.finally,we will use the ideas in this chapter to
continue our study of rectiltnear motion and to examine some consequences
of the chain rule in integral calculus.
