This has been , more often than not , the status message of my yahoo messenger for more than six months.

Many people have asked me about this. They have asked question like... why a sine wave why not a cos wave? To which i have replied its sine wave... coz... cos is sin( theta + - 90).

The point that i want to make is that not many people have asked me why "Life" is a sine wave?

My response to which would be take a whole day as a sample time and start the experiment. Obsevables: Events that makes you happy or make you sad. Remember this that every other event can be represented as the linear combination of these two basic emotions.so event which made you angry = a. ( Happy) + b. ( Sad) where a and b might not be a constant.

Now just plot these events using matlab ( you can use excel also ) or simply take a 2 Rs graph paper and a pencil and scale and plot the graph. You will see the graph as a sine wave. The amplitude and frequency may be different but the graph will be essentially a sine wave.The reason behind this is that God never intended any one to be purely happy or purely sad. He made an "Imperfect world" and thus no day ....mark my word ( copy it in the word file and then select it and press Ctrl B and Ctrl U and if you wish Ctrl I ) ....No day will make you totally happy or totally sad.
