1
-1
ω
ω2
The values of x and y satisfying the equation
x = -1, y = 3
x = 3, y = -1
x = 0, y = 1
x = 1, y = 0
If z is a complex number, then is equal to
0
None of these
The no.of real roots of the equation x2 - 3|x| + 2 = 0 are
2
3
4
If n is any integer, then in is
i
1,-1
i,-i
1,-1,i,-i
will be real, if θ is:
2nπ
nπ + π/2
nπ
For real value of x, the function will assume all real values provided
a > b > c
a < b < c
a > b < c
a < c < b and a> c > b
If x2 - 3x + 2 be one of the factors of the expression x4 - px2 + q, then
p = 4 and q = 5
p = 5 and q = 4
p = -5 and q = -4
p = -4 and q = -5
The polar form of complex number 1 - i is
If |z2 - 1| = |z|2 + 1, then 2 lies on
a circle
the imaginary axis
the real axis
an ellipse
