Question

tg(x) + cotg(x) / sec(x) x tg(x) simplifique

Answer 1

$\frac{ \frac{sen(x)}{cos(x)} + \frac{1}{tan(x)}}{\frac{1}{cos(x)} + \frac{sen(x)}{cos(x)}} = \frac{\frac{1}{ \frac{sen(x)}{cos(x)} }}{ \frac{1}{cos(x)} } = \frac{cox(x)}{sen(x)} . \frac{cos(x)}{1} = \frac{2.cos(x)}{sen(x)}$ = 2.cotg(x)
