Where
Let n(t) be a fixed strictly positive continuous function on (a, b). define H, = L([a,b], 7) to be the space of all measurable functions f on (a, b) such that \n(t)dt <0. Define the inner product on H, by (5,9)n = [ f(0)9€)n(t)dt (a) Show that H, is a Hilbert space, and that the mapping U:f →nif gives a unitary correspondence between H, and the usual space L-([a, b]).

For any vector field F⃗ and any scalar function f we define a new field
a) Assuming that the appropriate partial derivatives are
continuous, show the following formula:
b) Let ⃗x = x⃗i + y ⃗j + z ⃗k and the vector field
Use the formula found in a) to answer
the following question: is there a number p such that F⃗ is incompressible (that is, its divergence is zero)?
