Let, z = 32(cos 2800 + i sin 2800) = 32 cos(3600*n + 2800) + i sin(3600*n + 2800), wright here n is an integer.
⇒ z1/5 = < 32 cos(3600*n + 2800) + i sin(3600*n + 2800) >1/5
From De - Moievere"s theorem.
z1/5 = 2
⇒ z1/5 = 2 cos(72n + 56) + i sin(72n + 56) , where n is an integer.answeredAug 4, 2014by lillyExpert Please log in or register to include a comment.
