functions.... 3 questions

solution 2....

nishant bhaiya's rep::

Such questions are sort of standard question...

see the trick is to keep substituting x with something such that it becomes the next term...

first subst x=(x-1)/x

you get an equation
u will get f(1/(1-x))+f(1-1/x) = 1/(1-x)-x

then substract the second from the first equation

u will get f(x)-f(1/(1-x)) = x+1/x-1

Now put x=1/(1-x) again using the same trick as above....

u will get f(1/(1-x))-f(1-1/x) = 2-1/x

The 2nd and 4th are simultaneous..

U can go on to get it in a single term.. I hope this helps u get the full solution

hey gr8.. u had his answer saved!
