We have previously seen how a parabola is defined in terms of parametric equations.
In this section we will look at further aspects of parabolas:
- The Cartesian equation of a parabola.
- The parabola as a locus - the focus and directrix.
- The effect of the parameter $a$ on a parabola - all parabolas are the same shape.
- Tangents and normals of a parabola.
