Functional & Nonfunctional Requirements
• Functional Requirements: Actions that a system must be able to perform without taking physical constraints into considerations.
• Nonfunctional Requirements: Describe the required attribute of the system (performance, security, etc.).
With Use Case
• Use cases place the functional requirements into the context of a user.
• Use case can also be used to capture any nonfunctional requirements that are specific to the use cases.
Misconceptions related to Use Cases
• Use cases are nothing else than capturing functional requirements.
• Nonfunctional requirements are captured apart from the use cases.

∙ 12y agofunctional requirements are those requirements that were designed for or capable of a particular function or use. example: data capture, data inquiry, printing of reports, among others.
On the other hand, non-functional requirements are those requirements not having or performing a function. example: application artifacts/objects.

What is the difference between functional and non functional testing?
The difference between functional and nonfunctional is ... functional mostly depends on the domain or x- value in a coordinate- (x,y). I one of the x-values are the same number then the equation becomes NONFUNCTIONAL-for example: (-2,4), (-1,9) (-2,5). Those coordinates would be nonfunctional because there were 2 (-2s). It doesn't matter if the y value -(x,Y) is the same just as long as the x values are differnt numbers it will be functional.

How do you know nonfunctional requirements efficiently at initial stages in software engineering?
Non-functional requirements that affect virtually all projects fit into one of the following categories:PerformanceAvailabilityCapacityContinuitySecurityPerformance is a customer requirement and is generally obvious. The other 4 have your operations department as their customer. You can figure out all the less obvious non-functional requirements before you start coding by sitting down with your operations folks.Essentially anything that the operational people need to install and configure the software, monitor it, manage capacity, and fail over are non-functional requirements.All the above non-functional requirements are very difficult to add to a project if they are not engineered into a solution from the initial design of the architecture.
