Question: Let / be the distance from the origin to the point (x, y, z) in 3-D space, so that = x + y + z

Let / be the distance from the origin to the point

(x, y, z) in 3-D space, so that = x + y

Let / be the distance from the origin to the point (x, y, z) in 3-D space, so that = x + y + z" Evaluate the Laplacian of / , that is - 3 , as a function of / alone. az Adding these three second partials, we obtain dx
