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 r6656 = ky;
        double r6657 = sin(r6656);
        double r6658 = kx;
        double r6659 = sin(r6658);
        double r6660 = 2.0;
        double r6661 = pow(r6659, r6660);
        double r6662 = pow(r6657, r6660);
        double r6663 = r6661 + r6662;
        double r6664 = sqrt(r6663);
        double r6665 = r6657 / r6664;
        double r6666 = th;
        double r6667 = sin(r6666);
        double r6668 = r6665 * r6667;
        return r6668;
}

(FPCore (kx ky th)
  :name "Toniolo and Linder, Equation (3b), real"
  :precision binary64
  (* (/ (sin ky) (sqrt (+ (pow (sin kx) 2) (pow (sin ky) 2)))) (sin th)))
