Question

2- Calcular o valor da tangente dos seguintes ângulos: 2π/3, 5π/6, 7π/6, 5π/4, 5π/3 e 7π/4

Answer 1

$\mathsf{tg(\dfrac{2\pi}{3})=-\sqrt{3}}$

$\mathsf{tg(\dfrac{5\pi}{6})=-\dfrac{\sqrt{3}}{3}}$

$\mathsf{tg(\dfrac{7\pi}{6})=\dfrac{\sqrt{3}}{3}}$

$\mathsf{tg(\dfrac{5\pi}{4})=1}$

$\mathsf{tg(\dfrac{5\pi}{3})=-\sqrt{3}}$

$\mathsf{tg(\dfrac{7\pi}{4}=-1}$
