Feeling somewhat masochistic, I be mainly trying to to solve Beer-Monster's Little Problemo ! \lambda (x)= \left( {a}^{2}-{x}^{2} \right) \left( 1-c{x}^{2} \right) -(1) Taking derivative w.r.t.x of (1) f(x)=\lambda'(x)=-2\,x \left( 1-c{x}^{2} \right) -2\, \left( {a}^{2}-{x}^{2}...

I'm just TeX'ing away on the thin ice of a new Day ! \int _{0}^{1}\!{\frac {1}{\sqrt {{x}^{2}+{y}^{2}+{z}^{2}}}}{dx}=-1/2\,\ln \left( {y}^{2}+{z}^{2} \right) +\ln \left( 1+\sqrt {1+{y}^{2}+{z }^{2}} \right) Oo-er, me ickle preview, it preview-th not !
