The real part of the complex number is
1/4
1/2
tan θ/2
The value of (1 + i)8 + (1 - i)8 is
16
22
32
-32
Find the value of x and y if (x + iy) + (3 - 2i) = 1 + 4i
x = 6, y = -2
x = -2, y = 6
x = 3, y = -2
x = -2, y = 3
If we express ( 2 + 3 i ) 2 in the form of ( x + iy ) , we get
-5 + 12 i
12 - 5 i
5 - 12 i
12 + 5 i
Solution of √5 x2 + x √5 = 0 is
1 ± √19/5√5
-1 ± √19/2√5
-1 ± 5/2√5
None of these
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
If x is real, then the values of are
-1/3 and -1/13
1/13 and 1/3
-1/3 and 1/13
-1/13 and 1/3
The value of ω28 + ω29 + 1 is
1
0

ω2
The polar form of complex number 1 + √3 i is
cos (π/3)
sin (π/3)
cos (π/3) + i sin (π/3)
2[(cos (π/3) + i sin (π/3) ]
The polar form of number - 3 is
- 3 (cos π + i sin π)
3 (cos π+ i sin π )
√3[cos (2π/3) - i sin (2π/3) ]
2√3[ cos (2π/3) + i sin (2π/3 ) ]
