Hello,

I use some commands to generate a figure, as the picture illustrated, The equators of the two balls are solid lines.

It is not proper to demonstrate a 3D figure. I want to make parts of the equators become dash lines if they are...

Hello,

I use the commands below to generate a conical helix:

with(plots);
x := proc (t) options operator, arrow; t*cos(t) end proc;
y := proc (t) options operator, arrow; t*sin(t) end proc;
z := proc (t) options operator, arrow; t end proc;
spacecurve([x(t), y(t), z(t)], t = 0 .. 12*Pi, thickness = 5, color = blue, axes = normal, numpoints = 500);

Hello,

I use maplesim to simulate a simple delay system,as the document illustrated,I set the delay values from 0 to 4*Pi/(3*sqrt(3)) . I want to use a single souce to drive four branches, and use "probe" block to generate a figure which contains four curves according to different delays. So I use  a block "4-port Demultiplexer" which selected from Signal Blocks\Routing\Demultiplexers,...

Hello,

I have a transcendental equation

equ := 2+(s+1)*exp(tau*s) = 0

where s is a complex variable,and the range of tau is tau = 0 .. 1, I want to plot the trajectory of every roots,namely,s, in a complex plane according to the variety of tau. I try to use the command implicitplot, but get a curve in real plane.

Can you help me?

Best regards.

Hello,

there is a problem puzzling me, plot(tan(x),view=[-10..10,-10..10],discont=true) can plot tan(x) correctly, but when using smartplot(tan(x)),it yields an unexpected picture.

Is there any way to plot tan(x) correctly only using smartplot?

Thank you.
