Using "must" and "have got to" in a question

[kooper]

A grammar book I have been reading lately says it's rare to use "have got to" or "must" in a question. Use "have to" instead to make a question.

But I could find several sentences starting with "Must I ...?" "What have you got to...?" or "When has someone got to...?" through Google. So I'm a bit confused... Is what the grammar book says a fair statement?

It's not rare at all. It might be less common though.

Must you annoy me like that?!
Do you have to annoy me like that?!

Have you got to go to work tomorrow?
Do you have to go to work tomorrow?

All of these are correct, but the second in each case is probably more common in most places.
