1.	If cosx=2cosy−12−cosy, where x,y∈(0,π) and tanx2coty2=k, then the value of [k] is (where [.] represents greatest integer function)
Answer» If $cos x = \frac{2 cos y - 1}{2 - cos y}$ , where $x, y \in (0, π)$ and $tan \frac{x}{2} cot \frac{y}{2} = k$ , then the value of $[k]$ is (where [.] represents greatest integer function)
