please give me answer of maths question​ 3​

Answer 1

$\sf \: { \purple{To \: prove}} \\ \sf( \ \csc (o) - \cot(o) ) {}^{2} = \frac{1 - \cos(o) }{1 + \cos(o) } \\ \\ \sf \:{ \purple{ proof }}\\ \sf( \ \csc (o) - \cot(o) ) {}^{2} = ( \frac{1}{ \sin(o) } - \frac{ \cos(o) }{ \sin(o) } ) {}^{2} \\ \\ \sf( \ \csc (o) - \cot(o) ) {}^{2} = ( \frac{1 - \cos(o) }{ \sin(o) } ) {}^{2} \\ \\ \sf( \ \csc (o) - \cot(o) ) {}^{2} = ( \frac{1 - \cos(o) }{ \sin(o) } ) {}^{2} \\ \\ \sf \: by \: identity \\ \sf{ \purple{ \sin {}^{2} (o) + \cos {}^{2} (o) = 1}} \\ \\ \sf( \ \csc (o) - \cot(o) ) {}^{2} = \frac{(1 - \cos(o)) {}^{2} }{1 - \cos {}^{2} (o) } \\ \\ \sf \: by \: identity \\ \sf \: { \purple{{a}^{2} - {b}^{2} = (a - b)(a + b)}} \\ \\ \sf( \ \csc (o) - \cot(o) ) {}^{2} = \frac{(1 - \cos(o)) {}^{2} }{(1 - \cos(o)(1 + \cos(o)) } \\ \\ \sf( \ \csc (o) - \cot(o) ) {}^{2} = \frac{1 - \cos(o) }{1 + \cos(o) }$
