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 r2616 = x;
        double r2617 = 1.0;
        double r2618 = B;
        double r2619 = tan(r2618);
        double r2620 = r2617 / r2619;
        double r2621 = r2616 * r2620;
        double r2622 = -r2621;
        double r2623 = sin(r2618);
        double r2624 = r2617 / r2623;
        double r2625 = r2622 + r2624;
        return r2625;
}
