41. :I'm thinking that the term " field of rational functions " is really a misnomer. 42. Partial fractions are used in real-variable integral calculus to find real-valued antiderivatives of rational functions . 43. For subshifts of finite type, the zeta function is a rational function of " z ": 44. Iterated monodromy groups of rational functions usually have exotic properties from the point of view of classical group theory. 45. In the 1950s Myberg published several fundamental papers on the iteration of rational functions ( especially quadratic functions ). 46. The class contains the density functions of all distributions that have characteristic functions that are strictly proper rational functions . 47. In such cases, the integrand can be changed to a rational function by using the substitutions of Euler. 48. The order of the network is the order of the rational function describing the network in the complex frequency variable. 49. In particular, the zeroes of elliptic rational functions of order 2 ^ i3 ^ j may be algebraically expressed. 50. Let be a rational function of degree at least two, and assume that no iterate of is a polynomial.
