de valores notaveis. Dessa forma, complete a tabela de valores notáveis.​

Answer 1

Explicação passo-a-passo:

$\sf~~~~~~~~~~~~\Big|~~~~sen~~~~\Big|~~~~cos~~~~~\Big|~~~~~tg~~~~~\Big|$

$\sf~\Big|~~30^{\circ}~~\Big|~~~~~~\dfrac{1}{2}~~~~~\Big|~~~~\dfrac{\sqrt{3}}{2}~~~~\Big|~~~~\dfrac{\sqrt{3}}{3}~~~\Big|$

$\sf~\Big|~~45^{\circ}~~\Big|~~~~\dfrac{\sqrt{2}}{2}~~~~\Big|~~~~\dfrac{\sqrt{2}}{2}~~~~\Big|~~~~~~1~~~~~\Big|$

$\sf~\Big|~~60^{\circ}~~\Big|~~~~\dfrac{\sqrt{3}}{2}~~~~\Big|~~~~~~\dfrac{1}{2}~~~~~\Big|~~~~\sqrt{3}~~~~\Big|$
