If you wanna have 2 curves that are rotated 360 degress in one coordinate, then make 2 of them, and copy the one into the other one.

If you wanna have 2 curves that are rotated 360 degress in one coordinate, then make 2 of them, and copy the one into the other one.

Thank you very much for your quick answers.

I used the Visualization section, which says:

1. To use this 3D rotation feature I first need to enter:

with(Student[Calculus1]):

2. Then for horizontal rotation i need to enter this:

SurfaceOfRevolution(x^(2/3), x=0..1, output=plot);

Where "x^(2/3)" can be changed to another equation and the interval "x=0..1" can also be changed.

3. For vertical rotation i need to enter:

SurfaceOfRevolution(x^(2/3), x=0..1, axis=vertical, output=plot);

Maybe the other ones are better and more advanced, but I think that I'm going to use this simple one here.

Thanks.
