Exception for Rosa's DopplerBench

• Falling back on racket egraph because egg-herbie package not installed

Math

\[\frac{\left(-t1\right) \cdot v}{\left(t1 + u\right) \cdot \left(t1 + u\right)}\]

C

double f(double u, double v, double t1) {
        double r1675 = t1;
        double r1676 = -r1675;
        double r1677 = v;
        double r1678 = r1676 * r1677;
        double r1679 = u;
        double r1680 = r1675 + r1679;
        double r1681 = r1680 * r1680;
        double r1682 = r1678 / r1681;
        return r1682;
}
