Thanks a lot.

pointplot with symbol=solidcircle setting does give me a solidcirle when I use standard Maple interface. However, it works when I use Java interface. So I guess the standard interface does not support this?

I am wondering where I can find more information about the difference in standard and Java interface?



This is what I got. Do you have to load package or set some parameters?

Typesetting:-mrow(Typesetting:-mi("Here are integer 32 and float 3.14\n and expression "),Typesetting:-mfrac(Typesetting:-mi("π"),Typesetting:-mrow(Typesetting:-mn("1"),Typesetting:-mo("+"),Typesetting:-msup(Typesetting:-mi("x"),Typesetting:-mn("2")))))



iscont only works for 1-d. Is there a multivariate version of iscont? I hope to test the differentiability of a multivariate function over a region: x1=a1..b1, x2=a2..b2 ...... xn =



I see. Thanks a lot.


I tried

plot3d(sqrt(1-x^2 - y), x = -1 .. 1, y = -sqrt(1-x^2) .. sqrt(1-x^2),numpoints=5000);

but the surface still look awkward over the boundary.

Is there any Maple package to improve the quality of plot3d?


Is there any Maple package or command for plotting general polygons, given a set of vertices?
