Determine if you can find the line integral over the vector field F _c using the Fundamental Theorem of Line Integrals. If you cannot, find the line integral using conventional means.

a. (, , ) = (2y + ²) + (² + 2z) + (2z + ²), C is the curve, = 3 cos(t), = 3 sin(t), = ², 0 /2.

b. _c ² y + (2 3y)x, along C: =21x from (0, 0) to (4, 2).
