Limit

In summary, the purpose of finding limits in 2 minutes is to quickly and efficiently evaluate the behavior of a function at a particular point. Some tricks for finding limits in 2 minutes include using algebraic manipulation and known limit values or properties. There are also tips for finding limits in 2 minutes, such as practicing and utilizing shortcuts. While it is possible to accurately find limits in 2 minutes, it is important to double check the result and avoid common mistakes such as forgetting one-sided limits and not simplifying the function.

We might recognize the shape of a derivative.
$$\lim_{x\to\infty} x(e^{\frac 1x}-1)
=\lim_{x\to 0} \frac 1x(e^x-1)
=\lim_{x\to 0} \frac{e^x-e^0}{x-0}$$

This is the derivative of $e^x$ at $x=0$, which is $e^0=1$.
