The function is $\"\"$ .

\

Observe the graph :

\

The unbounded shaded region on interval $\"\"$ .

\

The area of the region bounded on $\"\"$ is $\"\"$ .

\

The function $\"\"$ is undefined at $\"\"$ .

\

If $\"\"$ is continuous on the interval $\"\"$ and has an infinite discontinuity at $\"\"$ , then

\

$\"\"$ , the limit exists then function is convergent.
