Question

qual a tangente de 300 ?

Answer 1

segundo a minha calculadora = -1.73

Answer 2

$\mathrm{tg\,}300^{\circ}\\ \\ =\mathrm{tg}\left(120^{\circ}+180^{\circ} \right )\\ \\ =\mathrm{tg\,}120^{\circ}\\ \\ =-\mathrm{tg}\left(180^{\circ}-120^{\circ} \right )\\ \\ =-\mathrm{tg\,}60^{\circ}\\ \\ =-\sqrt{3}\\ \\ \\ \boxed{\mathrm{tg\,}300^{\circ}=-\sqrt{3}}$
