See Explanation.
There seems to be some error in the Problem.
Please check the Problem.

If the Problem is correctly stated, then, it should hold good for every

#x in RR-{kpi}uu{(2k+1)pi/2), k in ZZ.#

Taking, #x=pi/3, the L.H.S.=sqrt3/(1+sqrt3/2)+(1/2)/(1-1/2)#

#=(2sqrt3)/(sqrt3+2)+1=2sqrt3(2-sqrt3)+1=4sqrt3-5#, while,

#The R.H.S.=1/sqrt3+2*2/sqrt3=5/sqrt3#.

#"So, The L.H.S."!="The R.H.S."#

Hence, there seems to be some error in the Problem.
