Question

Z=-3-i противоложное и сопряженное

Answer 1

я как раз про комплексные видео пишу

z=-3-i

-z=3+i - противоположное

z¬=-3+i - сопряженное

Answer 2

To find the opposite and the conjugate of a complex number, let's first understand what a complex number is. A complex number is represented as z = a + bi, where 'a' is the real part and 'b' is the imaginary part.

Given the complex number z = -3 - i:

1. Opposite of z: The opposite of a complex number is obtained by changing the sign of both the real and imaginary parts. So, the opposite of -3 - i is:

Opposite of z = -(a + bi) = -(-3 - i) = 3 + i

2. Conjugate of z: The complex conjugate of a complex number is obtained by changing the sign of its imaginary part while keeping the real part unchanged. So, the conjugate of -3 - i is:

Conjugate of z = a - bi = -3 - (-i) = -3 + i

In summary: Opposite of z = 3 + i Conjugate of z = -3 + i
