I'm trying to get the Lemniscate of Bernoulli moving in an x/y pictslider.

Can anybody help me to get the following equations into an expr object?

x = a*(the root of 2) * cos(t) / sin(to the power of 2)(t) +1

y = a *(the root of 2) * cos(t) * sin(t) / sin(to the power of 2(t) +1

x = a*(the root of 2) * cos(t) / sin(to the power of 2)(t) +1
y = a *(the root of 2) * cos(t) * sin(t) / sin(to the power of 2(t) +1

Here are more equations in case the one I posted doesn't work...

Awesome Volker, thank's a lot. I got it working.

Now I'd like to make the lemniscaat movement rotate clockwise or counter clockwise withing the pictslider.

Anybody an idea how I could make that work?
