__ABOUT__
Then one day....a miracle happened,....while applying a certain formula again and again.....I came to know its significance. Slowly and steadily....other equations also started clicking. I got to see a strong relationship between Maths and the Physics it was pointing towards. They both were the same. Maths was just an easy language to express a physical phenomenon. And a bit more to that in the sense that it could even predict the behaviour of a certain physical phenomenon. Equations now as if came to life.

Every equation now had as if something to say. A burning urge to share these things with the world aflamed within me. So that no one has to give up the subject that he or she loves the most.

The book on visualizing maths thus got written as a sprout of inspiration. The blog followed. Both these are dedicated to you and all such similar minds searching for answers.

why nature gives much preference to sine wave because all the changes in nature always in the sine wave.

ReplyDeleteHi,

DeleteGanesh Naik.

Your question is valid. Nature doesn't give preference to sine waves.

A cos wave for example is nothing but a sin wave delayed or advanced by 90 degree.

Imagine you have to plot a wave on a graph.

CASE 1

You start plotting such that at the starting point (origin ) of the graph..the wave is at point zero. (AT x=0 ,...y = 0)

At x=0....y=0

i.e maybe at time = 0 sec .....the wave-height = 0.

Such a wave that is at zero point at the beginning of the graph is a sinewave.

Case 2

You start plotting the wave such that at the beginning of the graph i.e at x = 0 or time = 0....the wave is at the highest point i.e at 90 degrees.

So at time = 0 sec....the wave is at y = 90 degrees.

(AT x=0,....y=max = maximum possible height of wave.)

Such a wave is a Cos wave.

So there is no much difference between a sine wave or a cos wave. It just depends upon from where you start plotting.

I hope I interpreted the question properly.
