Remove division symbol from infinitesimals example. #348

Closed beastaugh closed 10 months ago

beastaugh commented 10 months ago

Since division is a partial function it shouldn't have a function symbol in the language of Q (i.e. the first-order language of ordered fields).

This commit removes the symbol from the signature but tries to retain the intuitive quality of the example as it currently stands.
