Equation of Cissoid of Diocles in Cartesian Form: Also presented as
The Cartesian equation for the cissoid of Diocles can also be defined as:
- $y^2 = \dfrac {x^3} {2 a - x}$
or:
- $y^2 \paren {2 a - x} = x^3$
which can be derived directly from the form given by subtracting $x y^2$ from both sides and rearranging.
