1) Qual é a forma algébrica do complexo : 4 ( Cos 2π /3 + i. Sen 2π /3) * z = -2 + 2√3 i
z = 2 - 2√3 i
z = 2 + √3 i
z = -1 - 2√3 i
z = -2 - √3 i
2)O número complexo z = √2 + √2 i , na forma trigonométrica, é: *
2( Cos π /6 + i. Sen π /6)
2( Cos π /4 + i. Sen π /4)
2( Cos π /3 + i. Sen π /3)
2( Cos 3π /4 + i. Sen 3π /4)
2( Cos 5π /4 + i. Sen 5π /4)
3) Qual é a forma trigonométrica do complexo z = 1 + i *
2( Cos π /4 + i. Sen π /4)
4( Cos π /2 + i. Sen π /2)
√ 2( Cos π /4 + i. Sen π /4)
√3 ( Cos 2π /3 + i. Sen 2π /3)
√ 3( Cos π /6 + i. Sen π /6)
4)Qual é a forma algébrica do complexo z = 6( Cos 5π /6 + i. Sen 5π /6) *
z = 2 - 2√3 i
z = 3 - 3√3 i
z = -3 - 3√3 i
z = -3 + 3√3 i
z = -2 - 2√3 i
5) Qual é a forma trigonométrica do complexo z = -5i? *
5( Cos π /4 + i. Sen π /4)
5( Cos 3π /4 + i. Sen 3π /4)
5( Cos 3π /2 + i. Sen 3π /2)
5( Cos π /2 + i. Sen π /2)
5( Cos 3π /5 + i. Sen 3π /5)
