- Let be a positive number. Then the equation is the equation of an ellipse. Find (in terms of ) the eccentricity and the foci of this ellipse.
- Find a Cartesian equation for the hyperbola with the same foci as in part (a) and which has eccentricity .
Incomplete.
a) divide by p(p+2) to get the usual form of equation.
b) c=sqrt(2)=|a|sqrt(3)
