Question from Rahul:
I am not able to understand the following,
To prove that if for all e>0, x<e, then x=0, the contrapositive approach is used as follows,
assume x =/= (not equal to) 0 and hence we can take e=x>0, then x>=e. I understand the approach very well but I do not understand why if x=e then x>=e. If it is so then why not x=<e etc.
Thanks in advance!'
Rahul.
