Answer 1

Respuesta:

$\cot(60)^{2} \times \cot(30)^{2} \\ {( \frac{1}{ \sqrt{3} } )}^{2} \times {( \sqrt{3)} }^{2} \\ \frac{1}{3} \times 3 = 1$

$\tan(30) \times \cot(60) = x \\ \frac{1}{ \sqrt{3} } \times \frac{1}{ \sqrt{3} } = x \\ \frac{1}{3} = x$

$\frac{ \tan(30) }{ \cot(60) } + \frac{ \sin(60) }{ \cos(30) } -2 \\ \frac{ \frac{1}{ \sqrt{3} } }{ \frac{1}{ \sqrt{3} } } + \frac{ \frac{ \sqrt{3} }{2} }{ \frac{ \sqrt{3} }{2} } - 2 \\ 1 + 1 - 2 = 0$

$\sin(30)^{2} + \sin(60)^{2} - 1 \\ {( \frac{1}{2}) }^{2} + {( \frac{ \sqrt{3} }{2} )}^{2} - 1 \\ \frac{1}{4} + \frac{3}{4} - 1 \\ 1 - 1 = 0$
