Ans:
If the given function in the limit is of zero by zero form, then we can apply L’Hospital rule which is explain below
L = \lim_{x\rightarrow a}\frac{f(x)}{g(x)}
f(a) = 0
g(a) = 0
L = \lim_{x\rightarrow a}\frac{(f(x)-0)}{(g(x)-0)}
L = \lim_{x\rightarrow a}\frac{(f(x)-f(a))}{(g(x)-g(a))}
L = \lim_{x\rightarrow a}\frac{\frac{(f(x)-f(a))}{x-a}}{\frac{(g(x)-g(a))}{x-a}}
L = \lim_{x\rightarrow a}\frac{f'(x)}{g'(x)}
Similarly follow for higher derivative.
We keep on differentiating until we get an approriate answer.
