Mark the Correct alternative in the following:
If is a real number and 0 < θ < 2π, then θ =

For real number, imaginary part should be 0

⇒ 8 sin θ = 0

⇒ θ = n π

As θ belongs to (0,2π) so θ = π

Write the argument of

The value of (1 + i) (1 + i²) (1 + i³)(1 + i⁴) is

Mark the Correct alternative in the following:

If (1 + i) (1 + 2i) (1 + 3i) …. (1 + n i) = a + i b, then 2 × 5 × 10 × … × (1 + n²) is equal to

Mark the Correct alternative in the following:
