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 r8145 = x;
        double r8146 = 1.0;
        double r8147 = B;
        double r8148 = tan(r8147);
        double r8149 = r8146 / r8148;
        double r8150 = r8145 * r8149;
        double r8151 = -r8150;
        double r8152 = sin(r8147);
        double r8153 = r8146 / r8152;
        double r8154 = r8151 + r8153;
        return r8154;
}
