When you're trying to convince STEM professionals to go from hand written design documents to computer generated, you'd better be able to reproduce every little symbol that they're accustomed to using, or else it's just an excuse for non-compliance. Something like: (X+1)/X ≈ 1 for X ⋙ 1 We actually use a bit for showing derivation work on engineering design documents, especially for stating requirements for an equation to be valid. Or for equations that need to be simplified to be algebraically solved. A one line equation might have two pages of definitions, assumptions, and constraints. In this case, ⋙ is used to mean not just much greater-than, but big enough to justify whatever the simplification it is that you're making. Eg, 10 could be considered much greater (≫) than 1, but is still a 10% error in the equation above.
