Hi gomes,

If you are given an equation of the form:

with ,

you can determine the type of conic section just by considering the values of A and C.

If A = 0 or C = 0, but not both, then the conic is a parabola.

If A = C, then the conic is a circle.

If A and C have the same sign, but , then the conic is an ellipse.

If A and C have opposite signs, then the conic is a hyperbola.
