Detailed Solution for IIT JAM Mathematics Practice Test- 11 - Question 1

It is a well known theorem that A ⊂ R and D(A) is the set of all limit points of A, then 

IIT JAM Mathematics Practice Test- 11 - Question 2

Limit points of the sequence 

Detailed Solution for IIT JAM Mathematics Practice Test- 11 - Question 2

Here given set is 
Now fix m and vary n,
Let m = 1. then we have  clearly this sequence converge to 1
Thus 1 be limit point.
take m = 2. then we have  clearly this sequence converge to 1/2, so 1/2 be  a limit point.

So  1/3 be a limit point.
Thus the set of L.P. of given sequence is 
[Note : Whenever we have such question, in which we have two natural no's, then always keep one as fixed and varying other to find set of L.P.]
