Rephrase your question so it is comprehensible.
Ideally, functions should only be declared in a header and defined in a translation unit (source file) that includes the header. However, trivial functions are often defined in a header as they are usually good candidates for inline expansion, but you must remember to declare the function inline. Often it is better to forward declare inline functions so that maintainers are not distracted by the implementation details which can be placed towards the end of the header, out of the way. However, a definition is also a declaration, so forward declaring an inline function is not a requirement unless there is a cyclic dependency issue where a forward declaration is necessary to break the cycle.
sin, tan and cos can be defined as functions of an angle. But they are not functions of a triangle - whether it is a right angled triangle or not.
There are 2 types of library functions.One system defined & another user defined.In system defined functions we can not determine whether a library function is recursive or not.It may or may not be recursive.But in user defined library functions for example factorial() can be made recursive.No matters whether it is a library function.So if you understand recursion properly then this question makes no sense.
Trigonometric functions are defined from a numeric domain to a numeric range. So the input number determines whether or not the function is defined for that value and, if so, what the value of the function is.
If you graph the two functions defined by the two equations of the system, and their graphs are two parallel line, then the system has no solution (there is not a point of intersection).
The main program is itself just a function. Its only purpose is to serve as the entry point of the application. All other functions, whether built-in or user-defined, are just ordinary functions that can be called at any time so long as they are within the scope of the caller.
Language is human communication through the use of a system of signs, whether through audible vocal sounds, movements of the body, or through visual or tactile symbols. A language is a single system of signs employed for communication among a particular group of people of a given geographical area.
No
If there exists even one single item for which you cannot say whether it is in the set or not, the set is not well defined.
"Non-polynomials" may be just about anything; how alike or different they are will depend on what specific restrictions you put on such functions, or whether you are even talking about functions.

The will must be specific as to whether the gift is a life estate. If the gift is not defined as a gift for life then it will become the beneficiary's property absolute.The will must be specific as to whether the gift is a life estate.
