Question

Csc (x) + sec (x) /1+ tan (x)= csc(x) ​

Answer 1

Explicación paso a paso:

$\csc(x) + \sec(x) = \csc(x)(1 + \tan(x) ) \\ \frac{1}{ \sin(x) } + \frac{1}{ \cos(x) } = \frac{1}{ \sin(x) } (1 + \frac{ \sin(x) }{ \cos(x) } ) \\ \frac{ \cos(x) + \sin(x) }{ \cos(x) } = \frac{ \cos(x) + \sin(x) }{ \cos(x) }$
