comment Comprehensive compilation of conic section formulae
@MvG, if memory serves, what I obtained the last time I looked into this was just as horrendous; thanks, nevertheless.

comment How to reconstruct a symmetric matrix given the eigenvalues and eigenvectors.
Normalize the eigenvectors so that they're mutually orthogonal, and assemble them in a matrix $\mathbf V$. Then with the diagonal matrix of eigenvalues $\Lambda$, form $\mathbf V\Lambda\mathbf V^\top$. I omitted a few details that you should fill in.

comment Usage of integration representation
"In numerical calculation?" - sometimes, yes. As an example, one of the integral representations for the Bessel function of the first kind lends itself to a very useful method for numerical evaluation using the trapezoidal rule.

@Asaf, anything is possible. I know you don't chat, so I don't have a way to drill you on what I've missed. :P
