When I take a Gaussian surface inside an insulating solid sphere, why does the outer volume have no effect on the electric field?
Say I try to find the magnitude of the electric field at any point within an insulating solid sphere. I know that in the case of a conductor, the electric field within it is 0. However, I ha... | common-pile/stackexchange_filtered |

Differentiable Complex Functions
Let $f(z) = u(x,y) + iv(x,y)$ be differentiable for all $z = x + iy$. If $$v(x,y) = x + xy + y^2 - x^2$$ for all $(x,y)$, find $u(x,y)$ and express $f(z)$ in terms of $z$.

Intersection between a set and its boundary is a closed set?
Is it possible to show that for a neither open nor closed subset $ A \subset \mathbb{R}^n$, $\partial A \cap A$ is a closed set in $\mathbb{R}^n$?
No. $A=\mathbb{Q}$ has $\mathbb{R}$ as its boundary so $A \cap \partial A = A$ is neither open nor closed.
