Question

Ребята, ОЧЕНЬ СРОЧНО, тригонометрия начало

Answer 1

Объяснение:

1) $\alpha = 2,5\pi=0,5\pi+2\pi=\frac{\pi}{2} + 2\pi.$ α₀ = п/2, n = 1

2) $\alpha=14,3\pi=0,3\pi+14\pi=\frac{3\pi}{10}+14\pi.$ α₀ = 3п/10 (0,3п), n = 7

3) $\alpha=-2,2\pi=-4\pi+1,8\pi=\frac{18\pi}{10}-4\pi.$ α₀ = 18п/10 (1,8п), n = -2

4) $\alpha=-19,7\pi=-20\pi+0,3\pi=\frac{3\pi}{10}-20\pi.$ α₀ = 3п/10 (0,3п), n = -10

5)$\alpha=-\frac{13}{4}\pi=-3,25\pi=-4\pi+0,75\pi=\frac{3\pi}{4}-4\pi.$ α₀ = 3п/4 (0,75п), n = -2

6)$\alpha=\frac{-23}{6}\pi= \frac{13\pi}{6}-6\pi=\frac{\pi}{6}-4\pi$ α₀ = п/6, n = -4.
