Question

Решите любые два, срочно пожалуйста!!!!!!!

Answer 1

1)
$\sqrt{3} \tan(2x) + 1 = 0 \\ 2x = z \\ \sqrt{3} \tan(z) + 1 = 0 \\ \tan(z) = - \frac{1}{ \sqrt{3} } \\ z = - \frac{\pi}{6} + \pi \: n \: \\ x = - \frac{\pi}{12} + \frac{\pi}{2} n$
n € z-целое

2)
$\sin(3x) = - \frac{1}{2} \\ 3x = t \\ \sin(t) = - \frac{1}{2} \\ t = - \frac{\pi}{3} + \pi \: n \\ 3x = - \frac{\pi}{3} + \pi \: n \\ x = - \frac{\pi}{9} + \frac{\pi \: n}{3}$
n €z-целое
