Is tanx a rational function

Witryna28 lis 2024 · Now let’s consider limits of rational functions. A rational function is the ratio of two polynomials. In the case of a single variable, x, a function is called a rational function if and only if it can be written in the form: where P (x) and Q (x) are polynomial functions in x and Q (x) is non-zero. The domain of f is the set of all values of ... In mathematics, a rational function is any function that can be defined by a rational fraction, which is an algebraic fraction such that both the numerator and the denominator are polynomials. The coefficients of the polynomials need not be rational numbers; they may be taken in any field K. In this case, one speaks of a rational function and a rational fraction over K. The values of the variables may be taken in any field L containing K. Then the domain of the function is the set of th…

Witryna9 kwi 2015 · Apr 9, 2015. Yes. It has a dicontinuity at every x for which tanx is not defined. These are the x for which cosx = 0. That is: tanx is discontinuous at every odd multiple of π 2. These point, of course, are not in the domain of tanx. The discontinuities are non-removable, infinite discontiuities. Answer link.
