Please help with precalc problems! : cheatatmathhomework – According to De Moivre's theorem, the nth roots of a complex number 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((280° + 360°k)/4) + isin((280° + 360°k)/4)), or: z*1* = 4(cos(280°/4) + isin(280°/4)) = 4(cos(70°) + isin(70°))Question 1024127: Find the cube roots of 125(cos 288° + i sin 288°).

SOLUTION: Find the cube roots of 125(cos 288° + i sin 288°). – 288 + 720 = 1008. 1008 / 3 = 336 (or -24, same thing) 5(cos -24 + i sin -24) is the third cube root.—-You could go on adding 360 then dividing the new sum by 3, but you would find that you are simply repeating the same angles (trig functions have a cycle of 360) In this way, you always find 2 square root, three cube roots, four 4th roots, etc.Find the cube roots of 125(cos 288° + i sin 288°).
