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?

It is kind of a side effect of how Graph draws functions when $matches[1] is $matches[1] or $matches[1] because the function only exists in one point. However if you change $matches[1] to $matches[1] you should be able to see it. You might want to increase $matches[1] to make the point larger. Of course you also have to enable $matches[1] in the $matches[1] dialog.
