HalfWit Posted October 18, 2013 Share Posted October 18, 2013 But that means a/i equals ai and -ai How do you figure that? If a/i = ai and you multiply both sides by i you get a = -a. Surely you don't believe that every number is equal to its negative. 1 Link to comment Share on other sites More sharing options...

Surely you don't believe that every number is equal to its negative. It's because of the ambiguity of square roots. Link to comment Share on other sites More sharing options...
