6. We express obligation or necessity with:

must (strong obligation or personal feeling of necessity) – e.g. We must follow the school rules, (obligation; I'm obliged to.); I must see a doctor soon. (I decide it is necessary.)

have to (external necessity) – e.g. I have to do my homework every day. (others decide it is necessary)

I've got to (informal; it's necessary) – e.g. I've got to leave early today.

Must is the Present Simple form. It borrows the rest of its tenses from the verb “have to”. To form questions and negations of have to we use do/does (Pres. S.) and did (Past S.).
