Question

determine sen 43π/6​

Answer 1

Resposta:

43π/6  =43*180/6 =1290

1290=n * 360 ==>n ~ 3,5833

pegue a parte inteira  o 3    ==> 1290-3*360 =210

210=180+30

sen(180+30)

= sen 180*cos 30 + sen 30 * cos 180

= 0 *√3/2 +(1/2)*(-1)=-1/2

Answer 2

Olá, tudo bem?

sen 43π/6

= sen [(7π + 36π)/6]

= sen (7π/6 + 36π/6)

= sen (7π/6 + 6π)

= sen (7π/6 + 3×2π)

= sen 7π/6

= — ½
