I'd say that nothing can be covered deeply in an introductory survey class. If it's being taught at the 101 level, the students don't yet have the math to scratch anything beneath the surface. And one of the points of op amps, if not the main point, is the correspondence between their mathematical representation, and their real world behavior.
There are entire books about op amps and their uses. They're a cornerstone of analog design.
