arglist = Table[Symbol["t" <> ToString[i]], {i, 1, 3}]
Evaluate[F @@ arglist] = Cos@(Plus @@ (arglist{1, 1, -1}))
{t1, t2, t3}
Cos[t1 + t2 - t3]

F[t1, t2, t3]
Cos[t1 + t2 - t3]

but have not been able to figure out how to make Mathematica do this. 
Tried using


which gives


but then I don't know how to set the t[i]'s in expressions similar to


thanks in advance
