Help Please.
If z is a complex number where neither Re(z) or Im(z) is zero and it is given that z+(1/z) is real, find modulus of z.
Thank you.

Is the answer 1? (If so Ill post solution)

I got 1 as well but the answer says i.

 

[Sy123]

I dont think the modulus can be i though, modulus is the the distance of z from the origin (polar form)
Hence it cant be i lol
Answer is wrong (and since you and I got same answers I will assume we are correct)
