It is a simple question, but I am not able to figure it out how the formula of phosphamic acid, which is developed from phosphoric acid. In other words, I want to know how to relate it with phosphoric acid? Also in naming some acids we use meta like in, trimetaphosphamic acid, my question is meta is used for what?

Please help me understand. Thanks.

From Merriam-Webster:

An acid $\ce{PONH2(OH)2}$ derived from phosphoric acid by replacement of one hydroxyl group by an amido group is called  phosphamic acid. It is also called phosphoramidic acid

For the 'meta' part, see this - What does the prefix meta mean in inorganic chemistry?
