I’m very new to IanniX so I have some basic question concerning equations of mathematic curves.

I would like to implement this
to IanniX, but I have problem with syntax. Instead of parametric equation above, Iannix uses different way to write equations which I don’t understand entirely.

But the thing is totally not working. The problem is, that when I hit ‘add math curve’ – curve from templates is appearing and no matter what I write after in ‘curve equation’ nothing changes.
