How do you describe functional requirements?
Functional requirements define the basic system behaviour. Essentially, they are what the system does or must not do, and can be thought of in terms of how the system responds to inputs. Functional requirements usually define if/then behaviours and include calculations, data input, and business processes.

What is the difference between functional design document and technical design document?
In short, the functional design specifies how a program will behave to outside agents and the technical design describes how that functionality is to be implemented in code.
