Help Center Help Center. Infinity results from operations like division by zero and overflow, which lead to results too large to represent as conventional floating-point values. Use the isinf function to verify that x is positive or negative infinity:. The exact bit-wise hexadecimal representation of this NaN value is,. Always use the isnan function to verify that the elements in an array are NaN :. However, in some special cases perhaps due to hardware limitations , MATLAB does not preserve the exact bit pattern of alternate NaN representations throughout an entire calculation, and instead uses the canonical NaN bit pattern defined above.

This page illustrates the syntax for computing limits at infinity as well as the output produced for limits of infinite value in each CAS. However, in the first and third examples the manner of divergence may be described as divergence to positive and negative infinity, respectively. In the second and fourth examples the divergence is due to inconsistent behavior to the left and right of the approach point, and undamped oscillation, respectively. In Octave and MATLAB a polynomial may be represented without the symbolic toolbox as an array of coefficients ordered from highest degree to constant term in a single row. The deconv command accepts two polynomials, encoded as above, and performs polynomial division. The invocation syntax is deconv numerator-polynomial , denominator-polynomial. By default, only the polynomial quotient is returned. But if the call provides a row array with two variables to store the command's output as below then the polynomial quotient is stored in the first variable, and the remainder in the second. Of course the results of polynomial division facilitate identification of dominant terms in rational functions corresponding to certain tendencies of the input. The symbol for infinity may be entered into a Mathematica notebook with the keyboard sequence Esc inf Esc and may be used as the approach point in a Limit[] computation. So it may appear that Mathematica has given an incorrect answer in the second computation above. Note, however, that the Limit[] command in Mathematica does not compute bidirectional i. If a direction is not specified, then the default direction from the right for finite approach points is used. This result is suggested by our previous graph. The Apart[] command computes the partial fractions decomposition of a rational function.

We have shown how to use the first and second derivatives of a function to describe the shape of a graph. In this section, we define limits at infinity and show how these limits affect the graph of a function. We begin by examining what it means for a function to have a finite limit at infinity. Then we study the idea of a function with an infinite limit at infinity. Back in Introduction to Functions and Graphs, we looked at vertical asymptotes; in this section we deal with horizontal and oblique asymptotes. We can extend this idea to limits at infinity. We now look at the definition of a function having a limit at infinity.

We now look at the definition of a function having a limit at infinity. However, a function may cross a horizontal asymptote. In fact, a function may cross a horizontal asymptote an unlimited number of times.
