Complex numbers in “Named expressions”

  Hello everyone,
  I was wondering if we can define complex numbers in "Named expressions". i would like to implement the following expression
  
  Re(390e^(4,56it)) i is the imaginary unit and t is the time and Re is indicating that I want the real part of this complex number for each t. My math are very rusty so I am not sure if I can implement it in a different way. Any advice will be much appreciated.
  
  Best regards

  Is there a reason why you cannot just change it to cosine? See here for the Euler notation.

    Hello NFlynn thank you for the answer,
    I made that realization few moments after I posted this. It has been a while since I have done something similar 😅

  I'm keeping out of the maths, thanks NFlynn! The question is really why do you need imaginary numbers: expressions tend to be used to report a value or set something and that tends to be "real". I've only ever seen imaginary numbers in control theory (lesson learnt - find a specialist) and the electrickery tools in Ansys (always find an expert!).
