.... $\frac{1+cosX}{senX}$ = $\frac{senX}{1-cosX}$

Answer 1

Explicación paso a paso:

$\frac{1+cosX}{senX}= \frac{senX}{1-cosX} \\ (1 - \cos(x))(1 + \cos(x) ) = ( \sin(x) )( \sin(x)) \\ 1 + \cos(x) - \cos( x ) - {( \cos(x)) }^{2} = ( \sin(x) {}^{2} ) \\ { - \cos {}^{2} (x) } + 1 = \sin {}^{2} (x) \\ \sin {}^{2} (x) + \cos {}^{2} (x) = 1$
