Question:
<p>Given, <span>\(a^2 + 2a + \csc^2\frac{x}{2} - (a+x) = 0\)</span>, then which of the following holds good?</p>
<p>(a) <span>\(a = 1; x \in [-1,1]\)</span></p>
<p>(b) <span>\(a = -1; x \in [-1,1]\)</span></p>
<p>(c) <span>\(a \in \mathbb{R}; x = 0\)</span></p>
<p>(d) a, x are finite but not possible to find</p>
Step-by-Step Solution
Key Concept: Use properties of cosecant and analyze the quadratic equation to find constraints on a and x.
