first of all, limit tends to zero not one

By assuming it is 0, we use the special limit formula given by:-

Lim. f(x). =Lim. f'(x)
x->0. g(x). x->0 g'(x)

(We differentiate the numerator and denominator)
By that,

we get the equation equal to

1/(2* root(x+1)) - 1/(2* root(x-1))
The equation is not in 0/0 form anymore, we keep the limits which evaluates the answer equal to 0.

GeN21: multiply both numerator and denominator by root(x^2+1) + root (x^2-1)
GeN21: multiply the both term of numerator
GeN21: this will reduce numerator to a single term
GeN21: please ask it again.....post another question i will tell you there
