Parametrics Question (1 Viewer)

[VintageSquirtle]

In relation to Parametric Representation, do we need to know the parameterisation of a circle and a hyperbola? or just the parabola
ie
x = rcos(theta)
y = rsin(theta)

and

x = t
y = 1/t

You'll only need to know the parabola, but sometimes locus questions of other points related to this (intersection of tangents or normals) may turn out to be different curves (circles, hyperbolae, other curves that aren't standard conics).
