The answer is B,
Could you please show the steps to obtain the answer
2. Suppose that U(x, y, z) = x² + y²+ z² represents the temperature of a 3-dimensional solid object
at any point (x, y, z). Then
F(x, y, z) = -KVU (x, y, z)
represents the heat flow at (x, y, z) where K > 0 is called the conductivity constant and the
negative sign indicates that the heat moves from higher temperature region into lower temperature
region. Answer the following questions.
(A) [90%] Compute the inward heat flux (i.e., the inward flux of F) across the surface z =
1 - x² - y².
(B) [10%] Use the differential operator(s) to determine if the heat flow is rotational or irrotational.
Could you show why the answer is B
Using polar coordinates and the area formula
