Question

सिद्ध कीजिए cosA/1+sinA +1+sinA/cosA =2sinA​

Answer 1

$\frac{ \cos(x) }{1 + \sin(x) } + \frac{1 + \sin(x) }{ \cos(x) } \\ = \frac{ { \cos }^{2}x + {(1 + \sin(x)) }^{2} }{ \cos(x) (1 + \sin(x) )} \\ = \frac{{cos}^{2}x + {1}^{2} + {sin}^{2} x + 2 \sin(x) }{cosx(1 + \sin(x) ) } \\ = \frac{2 + 2 \sin(x) }{cosx(1 + \sin(x) )} \\ = \frac{2(1 + \sin(x) )}{ \cos(x) (1 + \sin(x)) } \\ = 2 \times \frac{1}{cosx} \\ = 2 \sec(x) \\ \\ hence \: proved$
