Question

Find the value of $\underset{h\to 0}{lim}[2-h]+\underset{h\to 0}{lim}[2+h]$

___

Answer 1

As we saw in the previous question [2-h], when h tends h tends to zero is 1 and [2+h] is 2.

$\Rightarrow \underset{h\to 0}{lim}[2-h]+\underset{h\to 0}{lim}[2+h]=\underset{h\to 0}{lim}1+\underset{h\to 0}{lim}2$

$=1+2$

$=3$
