Question: Factorise trigonometric terms

Hej!

I've some problems in factorising terms in an equation.

As one can see in the maple file below, the terms "cosh((1/2)*a+(1/2)*y)", "cosh((1/2)*a-(1/2)*y)", "sinh((1/2)*a+(1/2)*y)" and "sinh((1/2)*a-(1/2)*y)" recur in the equation. So want to factorise those terms, but it doesn't work with factor().

Does anybody have a solution, how I can simplify that equation?
