##

Eq= e^{t ( -h \pm \sqrt{ x} )}

##

I terms of ##Cosh (x) = e^x + e^{-x} /2 ##

The eqution can be written as:

##

Eq= e^{t( -h + \sqrt{ x} )} + e^{t( -h -\sqrt{ x} )}

##

Can this be written in terms of Cosh x ?

##

Eq= e^{t( -h + \sqrt{ x} )} + e^{t( -h -\sqrt{ x} )}

##

Can this be written in terms of Cosh x ?
