General solution is x=2npi+-pi/3x=2nπ±π3, where nn is an integer.

Explanation:

secxcscx=2cscxsecxcscx=2cscx

Hence, considering cscx!=0cscx0, secx=2secx=2

and so x=+-pi/3x=±π3 - note that csc(+-pi/3)!=0csc(±π3)0

and as all trigonometric functions are cyclic over 2pi2π,

General solution is x=2npi+-pi/3x=2nπ±π3, where nn is an integer.
