[math]\text{Curve((sec(π / 4 (1 / 2 - asind(cos(4n θ)) / π)); θ), θ, 0, 2π)}[/math]

(It's the previous one, with cosecant replacing the secant function)[br][br][math]\text{Curve((csc(π / 4 (1 / 2 - asind(cos(4n θ)) / π)); θ), θ, 0, 2π)}[/math]

Again, it's the top applet's one, with tangent replacing the secant function.[br][br][math]\text{Curve((tan(π / 4 (1 / 2 - asind(cos(4n θ)) / π)); θ), θ, 0, 2π)}[/math][br]
