It shows the real time of your computer; just check it!

The movement of the hour hand, minute hand and seconds' hand are controlled by *parametric equations.* The second hand moves 6^{0} every second.

Here is the **source code** for the animation. It is **JavaScript.**

<script type="text/javascript" >

var canvas = document.getElementById('myCanvas');

var context = canvas.getContext('2d');

var k;

function timing() {

//get date

var tme= new Date();

//get seconds

var s=tme.getSeconds();

//get minutes

var m=tme.getMinutes();

//get hours

var h=tme.getHours();

context.clearRect(0,0,500,500);

//seconds

context.beginPath();

context.arc(250,250,100,-Math.PI/2,[s*Math.PI/30]-Math.PI/2)

context.strokeStyle='red';

context.lineWidth=6;

context.stroke();

context.beginPath();

context.arc(250,250,70,-Math.PI/2,[m*Math.PI/30]-Math.PI/2)

context.strokeStyle='blue';

context.lineWidth=10;

context.stroke();

if(h<=12)

{

context.beginPath();

context.arc(250,250,40,-Math.PI/2,[(h)*Math.PI/6]-Math.PI/2)

context.strokeStyle='brown';

context.lineWidth=14;

context.stroke();

}

else

{

context.beginPath();

context.arc(250,250,40,-Math.PI/2,[(h-12)*Math.PI/6]-Math.PI/2)

context.strokeStyle='brown';

context.lineWidth=14;

context.stroke();

}

}

window.setInterval('timing()', 1000);

This is a vast collection of tutorials, covering the syllabuses of GCSE, iGCSE, A-level and even at undergraduate level.
They are organized according to these specific levels.

The major categories are for core mathematics, statistics, mechanics and trigonometry. Under each category, the tutorials are grouped according to the academic level.

This is also an opportunity to pay tribute to the intellectual giants like Newton, Pythagoras and Leibniz, who came up with lots of concepts in maths that we take for granted today - by using them to serve mankind.

~~"There's no such thing as a free lunch."~~

The best things in **nature** are free with no strings attached - fresh air, breathtakingly warm sunshine, scene of meadow on the horizon...

Vivax Solutions, while mimicking nature, offers a huge set of tutorials along with interactive tools for free.

Please use them and excel in the sphere of science education.

Everything is free; not even **registration** is required.

Maths is challenging; so is finding the right book. K A Stroud, in this book, cleverly managed to make all the major topics crystal clear with plenty of examples; popularity of the book speak for itself - 7^{th} edition in print.
