The graph of a function with a horizontal (y = 0), vertical (x = 0), and oblique asymptote (purple line, given by y = 2x) A curve intersecting an asymptote infinitely many times In analytic geometry , an asymptote ( / ˈ æ s ɪ m p t oʊ t / ) of a curve is a line such that the distance between the curve and the line approaches zero as one or ...
In other words, the function has an infinite discontinuity when its graph has a vertical asymptote. An essential singularity is a term borrowed from complex analysis (see below). This is the case when either one or the other limits f ( c − ) {\displaystyle f(c^{-})} or f ( c + ) {\displaystyle f(c^{+})} does not exist, but not because it is ...
The asymptotes of a truncus are found at x = -b (for the vertical asymptote) and y = c (for the horizontal asymptote). This function is more commonly known as a reciprocal squared function, particularly the basic example 1 / x 2 {\displaystyle 1/x^{2}} .
The function f(n) is said to be "asymptotically equivalent to n 2, as n → ∞". This is often written symbolically as f ( n ) ~ n 2 , which is read as " f ( n ) is asymptotic to n 2 ". An example of an important asymptotic result is the prime number theorem .
Instead, the function is said to "tend to infinity", denoted () =, and its graph has the line = as a vertical asymptote. While such a function is not formally defined for =, and the infinity symbol in this case does not represent any specific real number, such limits are informally said to "equal infinity".
Unconstrained rational function fitting can, at times, result in undesired vertical asymptotes due to roots in the denominator polynomial. The range of x values affected by the function "blowing up" may be quite narrow, but such asymptotes, when they occur, are a nuisance for local interpolation in the neighborhood of the asymptote point. These ...
This often happens when the function f being integrated from a to c has a vertical asymptote at c, or if c = ∞ (see Figures 1 and 2). In such cases, the improper Riemann integral allows one to calculate the Lebesgue integral of the function.
