# Thread: Carthesian equation of Talbot's curve

1. ## Carthesian equation of Talbot's curve

Hi!

I ask for the carthesian equation of Talbot's curve.

I know only its paramethrical equations

x=(1-a(sint)^2)cost
y=(1-a-a(cost^2)sint

2. Are you saying that x involves $sin^2(t)$ but that y involves $sin(t^2)$?
