If 3 cos x+sin x=2, then general value of x is(a) n π+-1nπ4, n � – InterviewSolution

1.	If 3 cos x+sin x=2, then general value of x is(a) n π+-1nπ4, n ∈ Z(b) -1nπ4-π3, n ∈ Z(c) n π+π4-π3, n ∈ Z(d) n π+-1nπ4-π3, n ∈ Z
Answer» If $\sqrt{3} \cos x + \sin x = \sqrt{2}$ , then general value of x is (a) $n π + {(- 1)}^{n} \frac{π}{4}, n \in Z$ (b) ${(- 1)}^{n} \frac{π}{4} - \frac{π}{3}, n \in Z$ (c) $n π + \frac{π}{4} - \frac{π}{3}, n \in Z$ (d) $n π + {(- 1)}^{n} \frac{π}{4} - \frac{π}{3}, n \in Z$
