Functional requirements describe function (mapping of inputs to outputs) of a system, what functions or services system should provide (to users).
Use cases describe how user (use case actor) could interact with the system, i.e. functionality of the system available to actors (human users or another systems), from the actor's point of view.
So, yes, use cases describe functional requirements. If we consider all functions provided by system as functions provided to actors - which is usually the case, use cases could be used to describe functional requirements of the system completely.

Functional and non functional requirements of web search engine?
There are many functional and non functional requirements of a web search engine. The non functional requirements would be the design you see, while the functional requirement would be the search bar.
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.
Explain why design conflicts might arise when designing an architecture where availability and security requirements are the most important functional requirements?
Availability can make security more difficult.
What is difference between software Requirement Specification and user requirement specification in software?
Software requirement specifications include both installation and maintenance requirements, and functional aspects of software that a user needs. User requirement specification in software is the specifications about functional and user interface specification.
What are the different types of use cases?
There are many types of cases depending what area one is talking about. There are storage cases, court cases, cd cases, glasses cases, stating cases, and nut cases.
What are non functional requirements and how do they relate to functional requirements?
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.

What are the deliverables in sdlc for requirement gathering and analysis phase?
The deliverables in the requirement gathering and analysis phase of the SDLC typically include a requirements document outlining business needs, functional requirements, non-functional requirements, and system constraints. Other deliverables may include use cases, user stories, workflow diagrams, personas, and a requirements traceability matrix to ensure alignment with project goals.
