Whenever you are free
Try to plant the tree
Biological world is a wonderful bowl
Since it is made up of many agreat soul
Human tendency is to inhale fresh air
But we get only apolluted air
None of them would like have tears

AN INTRODUCTION TO CIRCLE
Hellow my child it was being told
That you are so calm,quite and bold
You never seem's to be idle
Even since you were in the cradle
Most of the people will pat your back
If you are active round the clock.
Whenever I want to conduct a test
you must have an interest to perform best
Even if you are busy prepare the puddle
But you be firm and stand in the middle
Wait and see you feel the miracle
Think of its shape it looks like a circle.
All the vehicles that you feel
Ensure that Will have compulsiry a wheel
For a vehicle to have a motion
This circular wheels takes revolution
Let me know, are you studious
Then you gently walk along the radius.
Measure the arc length to have a fence
In Mathematics we call cicumference
Oh child the line that's intersecting boundary of a circle is a sword?
Certainly not,but it is the line segment that we call a chord.
Chord makes the circle into unequal parts
Whereas the diameter divides the circle into equal parts.
The maximum area is the major segment
The minimum area is the minor segment.
Which has the magnitude and direction is a vector
But a part of a circle is the sector
Co-incident lines have an angle zero degree,
Where as the central angle of a circle is 360 degree

WOES OF A TREE
WOES OF A TREE
Ready to serve with entire strength
My body is so hard looks like a drum
Even people cut me but i keep mum
My roots are scattered in the land
But I dont depend on your mind
My twigs are upside looking at the sky
Roots are downside peeping like a fly
Resourcess are limited over use is bad
Never be a crazy miss use is mad
Interdependency is the gift of god
allow to grow it so straight and bold
if you cut me happy to serve you
if you never touch ready to shelter you
if you crush me I cry like a widow
I am so generous you get my shadow
Limit your actions destroy the anger
Co-ordinate emotions controle the desire
You have freedom to enjoy the nature
But you dont have right to torture
Since the begining you enjoyed my beauty
Eaten my fruits but dont be naughty
If you are crueal in your heart so hard Icant guard
If you can pluck me but you fall ,in case you support me i will protect you and all .
