Question: How to perform 3d plot using three basic different plot

Hi Maple expert,

May I ask your time little bit, I am struggling with the 3D plot in maple, for basic 3D plot in maple is no problem for me, but this is a new case for me actually I want to perform a 3D plot based on these 3 different type of plots (or equations), here they are:

1. plot(2*(exp(-0.15*(u)^1.5))*(u)^0.5,u=0..2);

2. plot([0.2*(x-sin(x)),0.5*(1-cos(x)),x=0..10*Pi]);

3. polarplot(4+1*cos(5*x),x=0..2*Pi);

Can someone help me for this, many thanks for your help and time.
