Suppose that you are in a lab and you study a vector field F on Rº. From theoretical considerations, you know that the vector field is irrotational, and that it takes the form F(x, y, z) = (x + y², 2xy, a(x, y, z)), for some smooth function a : R³ → R. In your lab, you measure that: • The vector field vanishes at the origin; • Its divergence is V .F = 2x. Find the function a(x, y, z).

Question
Suppose that you are in a lab and you study a vector field F on R. From theoretical considerations, you know that the vector field is irrotational, and that it takes
the form
F(x, y, z) = (x + y², 2æy, a(x, y, z)),
for some smooth function a : R´ → R. In your lab, you measure that:
• The vector field vanishes at the origin;
• Its divergence is
V · F = 2x.
Find the function a(x, y, z).
