Question: Why will Maple not accept foci and MajorAxis arguments for defining an ellipse?

I try to define an ellipse using the geometry package

with(geometry):

ellipse(e1,['foci'=[[0,1],[4,1]], 'MajorAxis' = 8],[x,y]);

 

I get the message:  Error, (in geometry:-ellipse) wrong type of arguments

but the documentation tells me that I can define an ellipse this way...

 

Please Wait...
