No, this is the inverse of hyperbolic cosine.
Hyperbolic cosine is
and
See http://en.wikipedia.org/wiki/Hyperbolic_cosine.
The inverse of cosh can be obtained via algebra, letting .
But you can see the derivative of the inverse of cosh at that page, then via the chain rule you can solve this problem.
