Question

if a,b,c are complex numbers: prove: if |a|=|b|=|c|=1 then (conjugate of (a+b+c)) = (1/a) + (1/b) + (1/c)

Answer 1

if you can write these as
\[a=e^{i\theta}\] then you are done in one step i think

Answer 2

Answer 7

that might be true

Answer 8

I think I'm getting somewhere with the complex exponential function

Answer 9

I've got it, thanks for the hint!
