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 r8084 = e;
        double r8085 = v;
        double r8086 = sin(r8085);
        double r8087 = r8084 * r8086;
        double r8088 = 1.0;
        double r8089 = cos(r8085);
        double r8090 = r8084 * r8089;
        double r8091 = r8088 + r8090;
        double r8092 = r8087 / r8091;
        return r8092;
}
