curve from equation

[Israr]

I have two question about this image;


minus sign before equal sign, is it a bug. I am using WF 2.0 M180


and another question; can we use the internal local parameters shown in this image outside?

I have tried to create similar relations, and minus sign before equal sign is show where value of parameter is negative, although before mine parameter there is $ so this parameter could be negative.
Try look at relation, not in info, it might be a relation error if your parameter doesn't have $ sign before it.


Not sure about your other question, can you elaborate it a little bit?
