Topic: Re and Im parts of a complex number not showing

Ivan

  Hi. I am using the Beta version 4.5, build 584. When I input x(t)=re(3-2i) and y(t)=im(3-2i) as a parametric function nothing appears on the graph. I would have expected to see some sort of marker at x = 3 and y = -2. Is this a problem at your end or am I doing something wrong?

Re: Re and Im parts of a complex number not showing

It is kind of a side effect of how Graph draws functions when Draw type is Automatic or Lines because the function only exists in one point. However if you change Draw type to Dots you should be able to see it. You might want to increase Width to make the point larger. Of course you also have to enable Calculate with complex numbers in the Edit|Axes dialog.
