Following function provides a demonstration to use Java Script Math object

<script type="text/javascript">

        function mathLibrary() {

            document.write("Value Of Pie is--->  : " + Math.PI + "<br />");

            document.write("Squareroot of 81 is---->  : " + Math.sqrt(81) + "<br />");

            document.write("Value of Sin 60 is---->  :  " + Math.sin(60) + "<br />");

            document.write("Round of 5.7 is --->   : " + Math.round(5.7) + "<br />");

            document.write("Random number generated by Java Script is---->  :" + Math.random() + "<br />");
