Question 5. Consider the vector field
F = (2² + y? + z?)}(2, y, 2).
(a)
Using the component test, verify that F is conservative.
(b)
Find a potential function for F.
(c)
Let S be the quadric surface defined by (r - 1)² + (y + 1)² + 2z² = 18. Find the points q on
S where the integral
F. dr
attain its maximal and minimal values.
(Hint: Use theorems of vector calculus to reformulate this as a Lagrange multiplier problem.)
