$\"\"$

The trigonometric inequlity is $\"\"$ .

Find the value of $\"\"$ which satisfy the above equation, where $\"\"$ in the interval $\"\"$ .

Graph :

Graph the function $\"\"$ .

Draw a line $\"\"$ on the graph.

$\"\"$

Observe the graph $\"\"$ curve not intersect the line $\"\"$ .

Thus, $\"\"$ inequality does not have any $\"\"$ values.
