WebAccording to de Moivre's theorem, the nth roots of a complex number Z = r(cos θ + isin θ) are given by: = r 1/n (cos((θ + 2πk)/n) + isin((θ + 2πk)/n)). for integer k from 0 to n − 1. So in this case, n = 4. Thus, the four roots are of the form (256) 1/4 (cos((240° + 360°k)/4) + isin((240° + 360°k)/4)), => z*1* = 4(cos(240°/4) + isin(240°/4)) = 4(cos (60 °) + i sin (60 °) ) WebDec 7, 2016 · How do you simplify 2(cos 240 + i sin 240) ⋅ 3(cos 60 + i sin 60) and express the result in rectangular form?
