Pasos de solución

\frac{1 - cos ^{2} ( x )}{sin ( x )} + \frac{1 - sin ^{2} ( x )}{cos ( x )}

Mínimo común múltiplo de

sin (x), cos (x) : sin (x) cos (x)

Reescribir las fracciones basandose en el mínimo común denominador

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

Ya que los denominadores son iguales, combinar las fracciones:

\frac{a}{c} \pm \frac{b}{c} = \frac{a \pm b}{c}

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

1 - cos^{2} (x) cos (x) = sin (x) cos (x)

1 - sin^{2} (x) sin (x) = cos (x) sin (x)

= \frac{sin ( x ) cos ( x ) + cos ( x ) sin ( x )}{sin ( x ) cos ( x )}

Sumar elementos similares:

sin (x) cos (x) + cos (x) sin (x) = 2 sin (x) cos (x)
