```							hello harshitha thanks 4 d ques.we can write the eqn as4s^2 + 1/s^2 + t^2 + 1/t^2= 6 where s= sinx and t= tanxor (4s^2 + 1/s^2 – 4) + ( t^2 + 1/t^2 – 2)= 0(2s – 1/s)^2 + (t – 1/t)^2= 0since the sum of 2 squares can be zero IFF both of them are zero, so2s – 1/s= 0 and t – 1/t= 0or s^2= ½ and t^2= 1 or s^2/c^2= 1 or s^2= c^2 or 2s^2= 1 or s^2= ½ so, both the conditions give us the same result:s^2= ½ or sin^2x= sin^2(pi/4)or x= npi ± pi/4option 1kindly approve :)
