Question

sin A / 1 - cos A+ cos A/ 1 - tanA= sinA+ cosA​

Answer 1

Answer:

$\frac{ \sin(a) }{1 - \cos } + \frac{ \cos(a) }{1 - \tan(a) } = \sin(a) + \cos(a) \\ \\ \frac{ \sin(a) }{ \sin(a) } + 1 - \frac{ \sin(a) }{ \cos(a) } = \sin(a ) + \frac{1}{ \sin(a) } \\ \\ \frac{ \sin(a \cos(a +) ) + \sin(a \cos(a) ) + \ {}^{2} sin {}^{2} }{ \sin(a \cos(a) ) } = \frac{? { \sin } ^{2} a + 1 }{ \sin(a) } \\ \\ \frac{ { \sin }^{2} a + { \cos}^{2} a + { \sin}^{2} a}{? \sin(a \cos(a) ) } =$
