SIN&COS Function in VRML

Sin and Cos Function In VRML Format

To create this VRML structure such shown below, i have used these following Maple commands and options :

>restart;with(plottools):
vrml(plot3d(4*sin(s)+3*cos(t),t=-Pi..2*Pi,s=-2*Pi..2*Pi,
color=green,style=patch,coords=tangentsphere),
`plot3d.wrl`,background_color=COLOR(RGB,1,1,1),transparency=0.05):

The equation which i used to synthesize this 3D structure is simply written as
Y:=4*sin(s)+3*cos(t); in Maple worksheet.
Maple will assign the output as y:=4sin(s)+3cos(t)
