Does this function belong to an interesting class of functions?

We could argue that the value becomes 1 when [itex]\phi = 1[/itex] couldn't we?
No, you can't define a function one way and then argue that it has a different definition. You can, however, define a function that is 1 when [itex] \phi = 1 [/itex] and equal to -1 elsewhere. You can argue that this definition applies to a certain practical situation. That would be an argument about physics.
