Calling we can re-write that equation as

The only real solution is approximately
Going back to we have
Between and (between and radians) there are 4 angles with .
However, solutions to require positive tangent, so the only solutions will be in the first and third quadrants.
(or radians) is the approximate solution in the first quadrant.
(or radians) is the approximate solution in the third quadrant.
