FAQ
Frequently Asked Questions
Yes, though it is technical. It means 'to approach a line or value as a limit'. (e.g., 'The function asymptotes to zero.')
Yes, but it's a formal metaphor. It's used in sciences, economics, and formal writing to describe a process that approaches a limit without reaching it.
A limit is the value a function approaches. An asymptote is the actual line (often represented by an equation like y=c or x=a) that the graph of the function approaches.
In British English: /ˈæsɪm(p)təʊt/. In American English: /ˈæsɪm(p)toʊt/. The 'p' is often silent or very lightly pronounced.
A line that a curve approaches but never touches or intersects.
