The trigonometric equation is $\"\"$ .

Add $\"\"$ to each side.

$\"\"$

Divide each side by $\"\"$ .

$\"\"$

Since the period of the tangent function is $\"\"$ , the solutions on the interval are $\"\"$ and $\"\"$ .

The general solution of $\"\"$ is $\"\"$ , where $\"image\"$ is an integer.

The general solutions are $\"\"$ or $\"\"$ , where $\"image\"$ is an integer.
