In this video a plane is created on the sphere to obtain this surface. It is created in a way (time 5.24 - 6.56). I am able to create the same plane in a different way. I wish to know whether my one is correct to do so.

I can understand now, without using any plane you made it.
This is a simple methods. Thank you.
