Surface Command

Surface[ <Expression a>, <Expression b>, <Expression c>, <Parameter Variable 1>, <Start Value>, <End Value>, <Parameter Variable 2>, <Start Value>, <End Value> ]

Yields the Cartesian parametric 3D surface for the given x-expression a, y-expression b and z -expression c, using two parameter variables within the given intervals [Start Value, End Value].

Example: Surface[2 sin(t) * sin(v), sin(v), cos(v), t, 0, 2π, v, -π, π] creates the related surface in Graphics View 3D.

Note:

• End Value must be greater than or equal to Start Value and both must be finite.
• x, y and z are not allowed as parameter variables.
