eval(sin(x), x = .2) is evaluated, eval(sin(x), x = 4) is not evaluated. Why? What should we do to get the answer. x-2n k (pi) can be obtained and evaluated. Why Maplesoft does not simplify and evaluate?

Is there a way out to give proper command for Maple soft to know what to do?

Thanks for answer.
