1. This article elaborates the solution of asymptote of rational function curve, pointing out both the common way of finding limit value and the elementary way.

2. It is widely used to decompose a rational function into the sum of partial fractions.

3. On the issues the limit and range the rational function, Rawls insisted on constructive rationalism.

4. The positioning algorithm using Rational Function Model ( RFM ) of IRS - P 5 is described in detail.

5. It is widely used to decompose a rational function intosum of partial fractions.

6. The difficulty in decomposing rational function into partial fraction is to fix the undetermined coefficient in partial fraction.

7. There are also facilities to display the data's standard errors and select polynomial and rational functions.

8. The main reason is that the capital - circle did not form a rational function - system.

9. For continuous models, some methods for obtaining an approximated rational function using the continued fractions expansion technique and curve fitting techniques are studied.
