Question

If $sin space x plus cosec space x plus tan space y plus cot space y equals 4$ where x and y $element of open parentheses 0 comma pi over 2 close parentheses tan space y over 2$ s a root of the equation

$α^{2} + 2 α + 1 = 0$
$α^{2} + 2 α - 1 = 0$
$2 α^{2} - 2 α - 1 = 0$
$α^{2} - α - 1 = 0$

The correct answer is: $alpha squared plus 2 alpha minus 1 equals 0$
