A note on your new article

Hi Ahmed Magdy Hosny,

A couple remarks on your article Magdy's Exchanger:

• First, it is almost certain to be deleted, because Wikipedia is not a place for original research.
• Second, there are simpler ways to get to the same result. In particular, since $\sin(x)={\frac {\sinh(ix)}{i}}$ (where here $i={\sqrt {-1}}$ is the imaginary unit), one can immediately get a formula for the inverse sine from the formula for the inverse hyperbolic sine. In fact, your computations amount to this same procedure: in the expression in your article, the complex numbers are hidden inside the appearance of the expressions ${\sqrt {x^{2}-1}}$ and ${\sqrt {1-x^{2}}}$ -- for real x, one of these two symbols always denotes a purely imaginary number.

All the best, Joel B. Lewis (talk) 14:11, 14 May 2012 (UTC)
