Question 1189371: Express $\frac 1{1+\frac 1{1-\frac 1{1+i}}}$ in the form $a+bi$, where $a$ and $b$ are real numbers.
In case you have trouble reading that, here's the same expression written with the other type of fraction notation: 1/(1+1/(1-1/(1+i))).

Express $\frac 1{1+\frac 1{1-\frac 1{1+i}}}$ in the form $a+bi$, where $a$ and $b$ are real numbers.
In case you have trouble reading that, here's the same expression written with the other type of fraction notation: 1/(1+1/(1-1/(1+i))).
---------------------
This is just grinding it out.
Work right to left.

To start:
1/(1+i)
Multiply the DEN and the NUM by the conjugate of the DEN.
= (1-i)/((1+i)*(1-i) = (1-i)/2
