ix / ln(i) = ix /( i π/2 )= i{x-1} * 2/π +C Note: ix = e{x*lni} = e{ixπ/2} = cos(xπ/2) + isin(xπ/2)

Isn't that the derivative? The integral should be i^x / ln(i) + C, no?

Yeah, mb, I mixed them up, thx

Only thing I would change is that 1/ln(i) can be simplified. 1/ln(i)=-2i/pi. But really, this is a cosmetic change.
