Answer 2

HEYA!!!!

Here is your answer :
__________________________

From LHS :

$\sqrt{ \frac{1 + \cos}{1 - \cos} } = - - - - - \\ \\ rationalize \: the \: denominator \\ \\ = \sqrt{ \frac{1 + cos}{1 - cos} . \frac{1 + cos}{1 - cos} } \\ \\ = \sqrt{ \frac{ {(1 + cos)}^{2} }{1 - {cos}^{2} } } \\ \\ = \sqrt{ \frac{ {(1 + cos)}^{2} }{ {sin}^{2} } } \\ \\ = \frac{1 + cos}{sin} \\ \\ = \frac{1}{sin} + \frac{cos}{sin} \\ \\ = cosec + cot \:$

LHS = RHS
