You need to better understand the differences between \epsilon, \epsilon_{0} and \it{k}. Try http://en.wikipedia.org/wiki/Dielectric_constant" where \epsilon_{s} as given in their equation is what your equation calls \epsilon.
If you want to use that equation (and I would suggest that) then you need to figure out what your values of \epsilon and \it{d} are.
It would help to picture this capacitor that you're trying to build. From wikipedia:
You need to investigate what a dielectric is and how that relates...
I've been tasked with proving the existence of a full rank factorization for an arbitrary m x n matrix, namely:
Let \textit{A} \in \textbf{R}^{m x n} with \textit{rank(A) = r} then there exist matrices \textit{B} \in \textbf{R}^{m x r} and \textit{C} \in \textbf{R}^{r x n} such that \textit{A =...
