Exception for sintan (problem 3.4.5)

Math

\[\frac{x - \sin x}{x - \tan x}\]

C

double f(double x) {
        double r19575 = x;
        double r19576 = sin(r19575);
        double r19577 = r19575 - r19576;
        double r19578 = tan(r19575);
        double r19579 = r19575 - r19578;
        double r19580 = r19577 / r19579;
        return r19580;
}
