Construct the table for different values of $\"\"$ , to estimate the value of $\"\"$ : \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \

Observe the table.

\

As $\"\"$ tends $\"\"$ from left side, the value of $\"\"$ approaches to $\"\"$ .

As $\"\"$ tends $\"\"$ from right side, the value of $\"\"$ approaches to $\"\"$ .

\

Left side limit and right side limit are equal, $\"\"$ is exist.
