Consider 

f := t -> exp(-n*I*t)*(1+exp(exp(I*t)))/cosh(exp(I*t))/(exp(I*t*(1-n)) 
*(1+(exp(exp(I*t))-1)/(exp(2*exp(I*t))+1)));
simplify(f(t));

h := t ->(exp(-I*t)*(exp(exp(I*t))+exp(-exp(I*t))-2*cosh(exp(I*t))) /cosh(exp(I*t)));
simplify(h(t));

g := t -> (1/2)*(exp(exp(I*t))+exp(-exp(I*t)))/cosh(exp(I*t));
simplify(g(t));

I think every freshman equipped with a formulary can simplify this, 
unlike the "world's most powerful math engine".

Or did I miss something?

P.S.: If you want to know the solution try Wolfram/Alpha.
