(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Evalutate the limit, as x approaches 0, log(coshx)/x^{2}

2. Relevant equations

L'Hopital's rule

3. The attempt at a solution

I can get as far as (sinhx.cosh^{-1}x)/2x by differentiating the top and bottom separately. I'm not sure how to do the next differentiation.

Thanks for any help.
