asymptote

2 9.9
A straight line that a curve gets closer to but never touches or crosses
  • noun
  • /ˈæsɪmptoʊt/
  • Specialized
: asíntota
  • An asymptote can provide useful information about the behavior of a curve near its extremes.

Examples

  • So in calculus we define vertical asymptotes using limits.

  • The graph of the function approaches the asymptote but never actually touches it.

  • Let's shift this graph or the asymptote to the right one unit.

  • What's where should I draw the low frequency asymptote for that function?

  • Well, they look like that and they approach asymptotes, which are straight lines.

  • Both polynomials are second degree, so the asymptote is at y = 5.

  • In calculus, we often learn about horizontal asymptotes as the limits of functions at infinity.

Morphology

asymptote = a + symptote

The word is built from Greek combining forms (a- + symptote) that are not productive standalone English words, so learners cannot reliably derive the meaning from the visible parts.

Etymology

The word asymptote comes from a Greek phrase meaning 'not meeting': a- means 'not' and sym- means 'together', as in symmetry. So an asymptote is a line that a curve gets closer and closer to but never meets.
