Exception for math.sin on complex, real part

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

Math

\[\left(0.5 \cdot \sin re\right) \cdot \left(e^{0.0 - im} + e^{im}\right)\]

C

double f(double re, double im) {
        double r3840 = 0.5;
        double r3841 = re;
        double r3842 = sin(r3841);
        double r3843 = r3840 * r3842;
        double r3844 = 0.0;
        double r3845 = im;
        double r3846 = r3844 - r3845;
        double r3847 = exp(r3846);
        double r3848 = exp(r3845);
        double r3849 = r3847 + r3848;
        double r3850 = r3843 * r3849;
        return r3850;
}
