Aug 15, 16 · LIM‑1D2 (EK) Suppose we are looking for the limit of the composite function f (g (x)) at x=a This limit would be equal to the value of f (L), where L is the limit of g (x) at x=a, under two conditions First, that the limit of g (x) at x=a exists (and if so, let's say it equals L) Second, that f is continuous at x=LFeb 11, 19 · \(\lim_{x \to a} \frac{f(x)}{g(x)} = \frac{f'(a)}{g'(a)}\), if \(\lim_{x \to a} \frac{f(x)}{g(x)}\) gives the form 0/0 Where, f(a)=0 and g(a)=0 Limits of Exponential and Log Functions \(\lim_{x \to 0} e^{x}=1\) \(\lim_{x \to 0} \frac{e^{x}1}{x}=1\) \(\lim_{x \to \infty } \left ( 1\frac{1}{x} \right )^{x}=e\)According to the composition law, we have $$\lim\limits_{x \to 0}lnf(x) = ln\lim\limits_{x \to 0}f(x) = lnc$$ Because $\lim\limits_{x \to 0}g(x) = d$, we have $$\lim\limits_{x\to 0}g(x)lnf(x) = \lim\limits_{x\to 0}g(x)\cdot\lim\limits_{x \to 0}lnf(x) = dlnc$$ Apply composition lawagain, we get
