Question 1

Show that  div (r n r) = (n + 3) rn.
You may use the following fact: grad ( rn ) = n r n-2 r

Question 2

A vector field F is called solenoidal in a domain D if
div(F) = 0  in D
F = ∇ φ  in D for some scalar field φ
◦ ∇2F = 0  in D
grad(F) = 0 in D
curl(F) = 0  in D

Did you know?

It is believed that the Incas used anesthesia. Evidence supports the theory that shamans chewed cocoa leaves and drilled holes into the heads of patients (letting evil spirits escape), spitting into the wounds they made. The mixture of cocaine, saliva, and resin numbed the site enough to allow hours of drilling.

Did you know?

Oxytocin is recommended only for pregnancies that have a medical reason for inducing labor (such as eclampsia) and is not recommended for elective procedures or for making the birthing process more convenient.

Did you know?

Nitroglycerin is used to alleviate various heart-related conditions, and it is also the chief component of dynamite (but mixed in a solid clay base to stabilize it).

Did you know?

Inotropic therapy does not have a role in the treatment of most heart failure patients. These drugs can make patients feel and function better but usually do not lengthen the predicted length of their lives.

Did you know?

Sperm cells are so tiny that 400 to 500 million (400,000,000–500,000,000) of them fit onto 1 tsp.
