The values of x and y satisfying the equation are
x = 1, y = 3
x = 3, y = -1
x = 0, y = 1
x = 1, y = 0
Let z1 be a complex number with |z1| = 1 and z2 be any complex number, then
0
1
-1
2
If Z is a complex number such that , then
z is purely real
z is purely imaginary
z is any complex number
real part of z is the same as its imaginary part
If z is a complex number such that Re(z) = Im (z), then
Re (Z2) = 0
Im (z2) = 0
Re (z2) = Im (z2)
z2 = 0
then x + y is equal to
-2/5
6/5
2/5
-6/5
Express in the standard form .
1-3i
1+ 3i
-1-3i
None of these
If Z = r (cos θ + i sin θ), then the value of is
cos 2 θ
2 cos 2θ
2 cos θ
2 sin θ
If Z1=2 + i, Z2 = 3 - 2i and Z3 = -1/2 + √3/2 then the conjugate of z1z2 is
i
8 + i
8 - i
6 - i
The additive inverse of 1 - i is
0 + 0i
-1 + i
The modulus of is
√2
3
√3
