Limit Calculator
Calculate limits step by step
This free calculator will try to find the limit (two-sided or one-sided, including left and right) of the given function at the given point (including infinity), with steps shown.
Different techniques are used to handle limits (including indeterminate forms): limit laws, rewriting and simplifying, L'Hôpital's rule, rationalizing the denominator, taking natural logarithm, etc.
Solution
Your input: find $$$\lim_{x \to \infty} \frac{1}{x}$$$
The limit of a quotient is the quotient of limits:
$${\color{red}{\lim_{x \to \infty} \frac{1}{x}}} = {\color{red}{\frac{\lim_{x \to \infty} 1}{\lim_{x \to \infty} x}}}$$
The limit of a constant is equal to the constant:
$$\frac{{\color{red}{\lim_{x \to \infty} 1}}}{\lim_{x \to \infty} x} = \frac{{\color{red}{1}}}{\lim_{x \to \infty} x}$$
Constant divided by a very big number equals $$$0$$$:
$${\color{red}{1 \frac{1}{\lim_{x \to \infty} x}}} = {\color{red}{\left(0\right)}}$$
Therefore,
$$\lim_{x \to \infty} \frac{1}{x} = 0$$
Answer: $$$\lim_{x \to \infty} \frac{1}{x}=0$$$
