Exception for VandenBroeck and Keller, Equation (24)

• Falling back on racket egraph because egg-herbie package not installed

Math

\[\left(-x \cdot \frac{1}{\tan B}\right) + \frac{1}{\sin B}\]

C

double f(double B, double x) {
        double r2640 = x;
        double r2641 = 1.0;
        double r2642 = B;
        double r2643 = tan(r2642);
        double r2644 = r2641 / r2643;
        double r2645 = r2640 * r2644;
        double r2646 = -r2645;
        double r2647 = sin(r2642);
        double r2648 = r2641 / r2647;
        double r2649 = r2646 + r2648;
        return r2649;
}
