If conjugate and reciprocal of a complex number z = x + iy are equal , then
x + y = 1
x2 + y2 = 1
x = 1 and y = 0
x = 0 and y = 1
The additive inverse of -2 + 3 i is
2 + 3 i
-2 -3 i
2 - 3 i
-2 + 3 i
Determine x and y for which 2x + 3yi = 2+ 9i
x = 1, y = 3
x = 3, y = 1
x = 2, y = 1
x = 1, y = 2
The values of x and y, if 2x + 4i y = -i3 x - y + 3 are
1/3, 4/3
4/3, 1/3
2/3, 1/3
1/3, 2/3
