Part (e) – 4 points
The amount of paint needed for painting both sides of the fence is
(1) 5 L (Liters); (2) 5.2 L; (3) 3.2 L; (4) 4.3π L; (5) 3.2π L; (6) (160/50)π Liters
Question 4 (Section 16.4)
– 15 points
Use Green’s Theorem to find the work done by the force F(x, y) in moving a particle
from the origin along the bissectrice line x= y (in 1
st
quadrant) to the point (1, 1),
then along the line segment to the point (0, 1), and then back to the origin along the
y-axis, in other words, use Green’s Theorem to evaluate the line integral
Where the curve C is the described triangle, and
F(x, y) = (x
A
+ x
2
+ 1 + A)
A/2
i + tan
-1
x j
And, the value of A is the one determined in Question 1, Part (a).
