(3) Compute
f ds over the curve specified.
(a) f(x, y, z) = 2²,r(t) =< 2t, 3t, 4t > for 0 <t< 2
(b) f(x, y, z) = 2a² + 8z, r(t) =< e', t², t > for 0 <t < 1
For these last two problems find r(t) by parametrizing C.
(c) f(x, y) = VI+ 9æy, y = x³ for 0 < x < 1. (line integral for a function
of two variables is computed the same way as a function of three variables,
except C is on the xy- plane.
(d) f(x, y, z) = x + yz, and C is the line segment from P = (0,0,0) to
(6, 2, 2).
