People with emetophobia frequently report a vomit related traumatic event, such as a long bout of stomach flu, accidentally vomiting
Rational function the degree of formula_29 and both are real polynomials. The rational function is not defined at It is asymptotic to formula_32 as formula_33 The rational function is defined for all real numbers, but not for all complex numbers, since if "x" were a square root of formula_35 (i.e. the imaginary unit or its negative), then formal evaluation would lead to division by zero: which is undefined. A constant function such as "f"("x") = π is a rational function since constants are polynomials. Note that the function itself is rational, even though the value of "f"("x") is irrational for all "x".
