    \[\LARGE \frac{y^2}{4}-\frac{x^2}{4}=1\]

    This is the general form of equation for a hyperbola.. For circle it is,(x-a)^2+(y-a)^2=1

    So in order to find what it is, you divide the sides by the 4? @DLS

    Is that how you find out which conics is which? Simply divide what is whatever the number is to both sides?

    You have to observe and have an idea about all the conics.
