A) \[\varphi \]
B) \[\frac{\pi }{4}\]
C) \[\left\{ n\pi +\frac{\pi }{4}:n=1,\,2,\,3..... \right\}\]
D) \[\left\{ 2n\pi +\frac{\pi }{4}:n=1,\,2,\,3..... \right\}\]
Correct Answer: A
Solution :
\[\tan (3x-2x)=\tan x=1\] Þ \[x=n\pi +\frac{\pi }{4}\] But this value does not satisfy the given equation. Hence option (a) is the correct answer.
