How to see the content of a function handle?

Hi, I'm trying to create a function handle with 2 variables like x(1) and x(2) and use this function into next command lines to create other functions. for example assume these lines:

Dh = @(x) ((4*x(1)))/((x(1)+sin(x)));
G = @(x) (1/(10*x(1)));
Re = @(x) ((G(x)*Dh(x)));

Now, if i want to see the content of variable "Re", the MATLAB will answer like this:

    >> Re
    Re =

      function_handle with value:

        @(x)((G(x)*Dh(x)))

I want to see "Re" in mathematic shape like this:

          4
  ----------------
  10 x + 10 sin(x)

How can i do this? I'll be grateful for any help.

You would need the symbolic toolbox.

Dh = @(x) ((4*x(1)))./((x(1)+sin(x)));   %note correction to use ./ instead of /
G = @(x) (1/(10*x(1)));
Re = @(x) ((G(x)*Dh(x)));
x = sym('x', [1 2]);
pretty( Re(x) )

Perfect answer. Thank you.
