Exception for VandenBroeck and Keller, Equation (24)

Math

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

C

double f(double B, double x) {
        double r7974 = x;
        double r7975 = 1.0;
        double r7976 = B;
        double r7977 = tan(r7976);
        double r7978 = r7975 / r7977;
        double r7979 = r7974 * r7978;
        double r7980 = -r7979;
        double r7981 = sin(r7976);
        double r7982 = r7975 / r7981;
        double r7983 = r7980 + r7982;
        return r7983;
}
