Question

Which pair represents the same complex number?

Answer 1

For this case we have the following complex number:
 1 + i
 Its equivalent pair is given by:
 root (2) * (cos (pi / 4) + i * sin (pi / 4))
 Rewriting we have:
 root (2) * (root (2) / 2 + i * (root (2) / 2))
 (2/2 + i * (2/2))
 (1 + i)
 Answer:
 option A represents a pair with the same complex number

Answer 2

Answer:

1-i  and sqrt2cos(-pi/4)+isin(-pi/4)) is what mine said but it wasn't on here with the avalible options.
