DirectedInfinity[1 + I], why does it get replaced by (1 + I)/(sqrt(2) ?
Hello, This isn't particularly important probably, however, I am trying to learn as much about Mathematica as possible, and I thought this might shed some light on a 'Why Mathematica does this or that' principle. I'm working my way through 'The Mathematica Guidebook for Programming' and on page 177, he gives an example as follows: In:= DirectedInfinity[1 + I] DirectedInfinity[I] Out:= DirectedInfinity[-(1 - I)/sqrt(2)] That puzzled me a bit, so I decided to see what Mathematica would do with just the first part: In:= DirectedInfinity[1 + I] Out:= DirectedInfinity[(1 + I)/sqrt(2)] I realize that (1 + I)/sqrt(2) is in the same direction as (1 + I), but why did Mathematica change it to the more 'strange' form? Thanks, Matt
