Somewhere in my heart i have a feeling that this country is strange,
People help friends, and kill enemies,
who are all but the citizens of our mother earth.
We may be fighting wars with other countries but we are also in a war against poverty
While luxurious buildings spring up at a place, there is a dearth of houses in the other.
While biochemists are discovering new medicines, somewhere else new diseases are coming up.
We may boast that man has gone to the moon
but we need to be ashamed that he could not save millions of his brothers from poverty
There are droughts at many places and floods elsewhere
We may have the strongest nuclear weapons
but we may have the weakest citizens too.
Somewhere down my heart i feel that this country is strange.
           
COMMON ALL THE FUTURE CITIZENS OF INDIA LET US REALIZE THAT THE COUNTRY NEEDS OUR HELP.
 
LET US ALL TAKE A PLEDGE THAT WE WILL CONTRIBUTE OUR PART TO THE DEVELOPMENT OF THE COUNRTY AND THE WORLD.

for the burning desire a strong goal needs to be fixed (like"why do i need IIT")
honesty and hardwork are its consequences

the formula kq1q2/r(electrostatic potential should be used)
where k=9x 10^9
q1=q2=1.6x10^-19
r=3 angstroms
we get 7.68x10^-29x10^10=7.68x10^-19

IIT Jee is an easy exam!
Well not really but for the ones who are determined and are sincere it sure is.
It is certainly true that most of the IITians ate, drank and slept IIT i.e they always had only one thing in their mind and that is "IIT".
For those who think that they are studying for themselves or their parents , IIT would be a distant dream.
If one needs to have a clear goal, he needs self motivation every day and should study accordingly. Especially weeks before the exam one should practice lot of problems and increase his/her self confidence but should not be overconfident.
Many persons(including myself) ask the opinion of a book from many persons
While some tell that this is a good book, others tell that it is not good.
Here one has to go through the book himself and judge it accordingly. Taking advice from persons who have qualified JEE will be helpful.The book should be used in such a way that it leads to development of the required concepts systematically for the main exam. Finally, one should not depend on luck. If there is only one goal in your mind, luck always turns in your favour.
Keeping youself away from demotivators(those who try to decrease your self confidence) is also important.However as stated earlier do not be overconfident of yourself.
So, all the best for all the exams.
IIT is waitimg for YOU

on solving you get a quadratic in terms of x
solve it to get x in terms of y
range comes out to be (1/3,3)

the given function is a real value function for all values of x belonging to real number set.
reason is that the denominator is always positive and is defined for all values of x( you equate the denominator to zero and you get complex values of x, by solving the quadratic equation hence you can conclude that the denominator is imaginary only when x is imaginary, hence it is real for all real values of x and never equal to zero)
even if the numerator is zero(which is not in this case, the function will be defined and have a value=0)
to find the range take f(x) as some y
write x in terms of y and take x as a function of y and find the domain of x
note that in case there are some values of x where the fuction is not real, you have to exclude the corresponding values of y from the range. this can be done by substituting the x value for which the function is not defined (in the equation where x is f(y)) and finding the corresponding value y. in this problem there is no need to do so as y=f(x) is defined for all values of x.

R D Sharma is good for theory and subjective problems
However for more practice on objectives TMH 2008 edition is good
