Question

7- Determine o seu (25pi/12).​

Answer 1

Explicação passo-a-passo:

na na trigonometria vale 180

25×180/12 = 375°

Answer 2

Oie, Td Bom?!

$= \sin( \frac{25\pi}{12} )$

$= \sin( \frac{\pi}{12} + 2\pi)$

$= \sin( \frac{\pi}{12} )$

$= \sin( \frac{\pi}{4} - \frac{\pi}{6} )$

$= \sin( \frac{\pi}{4} ) \cos( \frac{\pi}{6} ) - \cos( \frac{\pi}{4} ) \sin( \frac{\pi}{6} )$

$= \frac{ \sqrt{2} }{2} \: . \: \frac{ \sqrt{3} }{2} - \frac{ \sqrt{2} }{2} \: .\: \frac{1}{2}$

$= \frac{ \sqrt{2} \sqrt{3} }{2 \: . \: 2} - \frac{ \sqrt{2} \: . \: 1 }{2 \: . \: 2}$

$= \frac{ \sqrt{6} }{4} - \frac{ \sqrt{2} }{4}$

$= \frac{ \sqrt{6} - \sqrt{2} }{4}$
