Example 3: Solving an Applied Problem Involving a Rational Function A large mixing tank currently contains 100 gallons of water into which 5 pounds of sugar have been mixed. A tap will open pouring 10 gallons pe
are points of the function that are "missing": around the point, the function appears normal, but at one particular value, the value of the function disappears. The simplest example would bef(x)=xx: clearly, this fraction can be reduced to 1. Is the graph of this function then simply ...

Functions that are the result of the division of two polynomials are rational functions, which can be solved by cross multiplying numerators and denominators. Review the definition of a rational function and learn how to solve rational equations and rational inequalities. ...
The problem to decide whether a given rational function in several variables is positive, in the sense that all its Taylor coefficients are positive, goes back to Szegő as well as Askey and Gasper, who inspired more recent work. It is well known that the diagonal coefficients of rational ...

complete the story until after the introduction of the inverse tangent function in Section 6.5. We begin with a few examples to illustrate how some integration problems involving rational functions may be simplified either by a long division or by a simple substitution. Example To evaluate , we ...
In this paper, by adding the lacking derivative conditions and setting the artificial interpolating values as undetermined parameters, we propose a parametric linearization method to convert the problem of finding a multivariate Birkhoff rational interpolation function into solving a parametric polynomial ...
