minimal surface of revolution meaning in Hindi

Examples

1. A minimal surface of revolution is the surface of revolution of the curve between two given points which minimizes surface area.
2. A basic problem in the calculus of variations is finding the curve between two points that produces this minimal surface of revolution.
3. There are only two minimal surfaces of revolution ( surfaces of revolution which are also minimal surfaces ) : the plane and the catenoid.
4. For a given constraint there may also exist several minimal surfaces with different areas ( for example, see minimal surface of revolution ) : the standard definitions only relate to a local optimum, not a global optimum.
