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 r5988 = x;
        double r5989 = 1.0;
        double r5990 = B;
        double r5991 = tan(r5990);
        double r5992 = r5989 / r5991;
        double r5993 = r5988 * r5992;
        double r5994 = -r5993;
        double r5995 = sin(r5990);
        double r5996 = r5989 / r5995;
        double r5997 = r5994 + r5996;
        return r5997;
}
