Answer 1

Ответ:

-1

Пошаговое объяснение:

-4 = 4(cosπ + isinπ)

z1 = √2(cos(π/4) + isin(π/4))

z2 = √2(cos(3π/4) + isin(3π/4))

z3 = √2(cos(5π/4) + isin(5π/4)) = √2(cos(-3π/4) + isin(-3π/4))

z4 = √2(cos(7π/4) + isin(7π/4)) = √2(cos(-π/4) + isin(-π/4))

максимальный аргумент: 3π/4

Re(z2) = √2cos(3π/4) = √2 * (-√2/2) = -1
