Your first impulse might be to change each tan(x) to sin(x)/cos(x). But that path will make the work much harder.

Take a look at the given terms and look for an easier way.



Factor out the common tan(x) on the left:



Now you might see a quick path to solving the equation -- there is a common factor of 2sin(x)-1:



OR

Presumably, if you are working on a problem like this, you know how to finish from there....
