If you let sqrt1+i=x+iy, then (x^2-y^2)+i2xy=1+i. then x^2-y^2=1 and 2xy=1. Hence (x^2+y^2)^2=(x^2-y^2)^2+4x^2y^2=2. Hence x^2+y^2=sqrt2. Now adding this two terms x^2=frac1+sqrt22 ...

arctan 2 is not a rational multiple of pi. If it were, then for some integer n > 0, we would have (1 + 2i)^n is real. On the other hand, if we define a_n := operatornameIm((1 + 2i)^n) ...
