Transcribed Image Text:8. Consider the curves given by y = sin(x) and y = cos(x). For each of the
following problems, you should include a sketch of the region/solid being
considered, as well as a labeled representative slice.
a. Sketch the region R bounded by the y-axis and the curves y
=
sin(x) and
y cos(x) up to the first positive value of x at which they intersect. What
is the exact intersection point of the curves?
b. Set up a definite integral whose value is the exact area of R.
c. Set up a definite integral whose value is the exact volume of the solid of
revolution generated by revolving R about the x-axis.
d. Set up a definite integral whose value is the exact volume of the solid of
revolution generated by revolving R about the y-axis.
e. Set up a definite integral whose value is the exact volume of the solid of
revolution generated by revolving R about the line y = 2.
f. Set up a definite integral whose value is the exact volume of the solid of
revolution generated by revolving R about the line x =
-1.
