Hi!
Excuse If I made something wrong but I wanted to ask you about a possibility to draw a diagram to show Im of z^4.
How to draw something similar on Wolfram Alpha? I mean the attached picture.
Thank you in advance.
Best wishes.
Henrik, I'm grateful to you for your help.
The only difference I made was about swapping {a,b} to {b,a}.
Thank you.
Hi Michael,
perhaps this is what you are looking for:
ContourPlot[Im[(a + I b)^4], {a, b} \[Element] Disk[], PlotTheme -> "Monochrome", PlotPoints -> 100, Contours -> #] & /@ {1, 5, 15}
which gives:
Regards -- Henrik
Thank you so much.
Is there any way to draw it using just black & white?
Perhaps something like
Plot3D[Im[(a + I b)^4], {a, -2, 2}, {b, -2, 2}]
