Exception for Trigonometry A

\[0.0 \le e \le 1\]

Math

\[\frac{e \cdot \sin v}{1 + e \cdot \cos v}\]

C

double f(double e, double v) {
        double r8095 = e;
        double r8096 = v;
        double r8097 = sin(r8096);
        double r8098 = r8095 * r8097;
        double r8099 = 1.0;
        double r8100 = cos(r8096);
        double r8101 = r8095 * r8100;
        double r8102 = r8099 + r8101;
        double r8103 = r8098 / r8102;
        return r8103;
}
