Topic: Imaginary numbers!?

Is it possible to calculate in Imaginary number?

...in Graph.


[ 3 (sqrt(3)+3i) ] , and
[ -5 (sqrt(3)+i) ] ?

Re: Imaginary numbers!?

Yes, if you for example insert the function f(x)=x and evaluate it at x=3(sqrt(3)+3i) and see that the result is f(x)=5.1962+9i. You can also evaluate f(x)=sqrt(x) for x=-9 and get the result f(x)=3i.
