Exception for Toniolo and Linder, Equation (3b), real

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

Math

\[\frac{\sin ky}{\sqrt{{\left(\sin kx\right)}^{2} + {\left(\sin ky\right)}^{2}}} \cdot \sin th\]

C

double f(double kx, double ky, double th) {
        double r6768 = ky;
        double r6769 = sin(r6768);
        double r6770 = kx;
        double r6771 = sin(r6770);
        double r6772 = 2.0;
        double r6773 = pow(r6771, r6772);
        double r6774 = pow(r6769, r6772);
        double r6775 = r6773 + r6774;
        double r6776 = sqrt(r6775);
        double r6777 = r6769 / r6776;
        double r6778 = th;
        double r6779 = sin(r6778);
        double r6780 = r6777 * r6779;
        return r6780;
}
