For conic section of the form:
The Ends of the Lactus Rectum is given as:
The e in the equation above is the Eccentricity of the Hyperbola.
This can be obtained by the formula:
Thus, comparing the standard form of the conic with the given equation, we have:
Then, we need to obtain the value of the Eccentiricity, e.
Hence, the coordinate of the ends of the each lactus rectum is:
