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 r7984 = 0.5;
        double r7985 = re;
        double r7986 = sin(r7985);
        double r7987 = r7984 * r7986;
        double r7988 = 0.0;
        double r7989 = im;
        double r7990 = r7988 - r7989;
        double r7991 = exp(r7990);
        double r7992 = exp(r7989);
        double r7993 = r7991 + r7992;
        double r7994 = r7987 * r7993;
        return r7994;
}
