comment Sin(x): surjective and non-surjective with different codomain?
+1 I added your key notice from your comment and tried to make things more explicit -- I read somewhere that set-theoretically there was someone about 1921 who differentiated the mathematical function as a triplet set from other functions. Feel free to correct my writing, thank you for your answer.

Added the key notice from the comment and made things more explicit: there is alternative notation for the triple set by some Russian mathematician about 1921, this could be an awesome point here for letting future readers to find historical background

comment Predicate logic for statements about functions?
Are you able to explain the trigometric function such as $sin(x)$ in terms of partial function, totality, partial bijection and well-defined for this?

comment Sin(x): surjective and non-surjective with different codomain?
@PeterFranek good point +1. What is the description about sin? Can it be explained with the concepts such as totality of function, partial functions, partial bijection and such terms? I added your point to a community wiki answer and I wanna understand the nature of functions such as sin deeper: the surjectivity and injectivity change with different codomain, interesting.

Misread wikipedia, it is correct.
