Correct syntax jquery accordion

Correct syntax jquery accordion

I use jquery accordion and it work properly, but I'd like to know if I used the correct syntax.

Here is the code:
  2. <head>
  3. <script>
  4.   $(function() {
  5.     $( "#accordion" ).accordion({
  6.        icons: { "header": "ui-icon-circle-triangle-e", "activeHeader": "ui-icon-circle-triangle-s" },
  7.        collapsible: true ,
  8.        active: true
  9.      });
  10.   });
  11. </script>
  12. </head>
