Homework Help: Naive question on plotting

  1. Dec 11, 2009 #1
    1. The problem statement, all variables and given/known data

    How do I plot a function with an imaginary term (e.g. a*exp (ix), etc.)? More importantly, how would I do it on a calculator.

    2. Relevant equations

    3. The attempt at a solution

    You don't - unless you do it in 3 dimensions using, say, the y- axis for the real part of the function value and the z- axis for the imaginary part of the function value. That, of course, assumes that the independent variable, x, is a real number since there is only one dimension left for it.

    I see. I am a bit confused, since I have a problem asking me to plot a function with an imaginary term. Perhaps I have done it wrong (though I have looked over it and cant find an error) or I must plot in three dimensions.
