center at (3,0, 0) and radius 2 on the plane r = 3 from the point (3,2, 0) to (3, -2,0); and C3 be
the line segment from (3,-2,0) to (3,0, 0).
(a) Draw a sketch of the curves C1, C2, and C3 in one 3-dimensional space R’.
(b) Give a parametric representations of C1, C2, and C3, and denote it by R, (t), R2(t), and Ra(t),
respectively.
(c) Evaluate the line integrals
x dx + z dy – xy dz,
for k = 1,2, 3.
(d) Calculate:
r dr + z dy – y dz,
where C = C1 + C2 + C3.
