Exception for Falkner and Boettcher, Appendix B, 2

Math

\[\left(\frac{\sqrt{2}}{4} \cdot \sqrt{1 - 3 \cdot \left(v \cdot v\right)}\right) \cdot \left(1 - v \cdot v\right)\]

C

double f(double v) {
        double r8608 = 2.0;
        double r8609 = sqrt(r8608);
        double r8610 = 4.0;
        double r8611 = r8609 / r8610;
        double r8612 = 1.0;
        double r8613 = 3.0;
        double r8614 = v;
        double r8615 = r8614 * r8614;
        double r8616 = r8613 * r8615;
        double r8617 = r8612 - r8616;
        double r8618 = sqrt(r8617);
        double r8619 = r8611 * r8618;
