Hi to all,

I'm trying to find a general formula for the taylor expansion around 0 of

ln(cos(x))

I know how to get the first terms yet no general formula for the series that i get

does anyone know how to do it?

Thanks, Lior

If you start with the Taylor series for

where are the Bernoulli numbers (see Taylor series - Wikipedia, the free encyclopedia)

then you can integrate term by term. - Feb 19th 2009, 05:20 AMturthanks
Thanks a lot.
