1i just tried i dnt noe if it dnt exist or not bt if it does then d answer is a for sure :)
write tan@ = x
n then itz easy :)
PS:: only if d limit does exist :P
62hmm.. i din notice.. but the problem is that the function is not defined at x=0
So i am sure the question has assumed the definition of tan inverse at x=0 as pi/2
which is essentially not correct..
This is like saying tan-1(1/0) = pi/2 when it should be not defined...
