Wish list for ggb4 or ggb5

When you plot a line or a parabola would it be possible to have the following extra options available for

Object Properties...Algebra tab...Equation pull down list


For a line: ax+by+c=0. In Australia this is referred to as the general form of a line.

For a parabola: y=a(x-h)^2+k. In Australia this is referred to as vertex form, with vertex (h,k) and axis of symmetry

x= -b/2a


Thanks.

These same forms are used in the US as well. I agree that the general and vertex forms should be added to the context menu as soon as it is possible/feasible. It would be a nice feature.

PS I have seen these forms used in applets from other countries, so I believe this would be beneficial.

Please try the new version 5.0.282.0. We now have

* New form for lines ax + by + c =0

* New forms for Parabolas (Conic Form and Vertex Form)
