I'm looking for a formula that draws several spirals when typed in, as you can see in the picture.

It goes without saying that several spirals can be represented if the figures are drawn separately and flipped one by one.

But it would be best to draw with a function. Probably the Euler-Maclaurin summary formula

maybe it would solve the problem if we applied it.

The internal properties of the spirals are thus determined by an internal function of the curvature factor dt/ds. I don't know how to give him that long formula. But it is also likely that a different summation formula is needed.

It would be advisable to use two solutions that can be used to solve things that, unfortunately, I only partially know about.

The sum function is again suitable for drawing functions iteratively, the only problem is that the function is an integer

returns a value, and you need fractional values here, otherwise the spiral will appear piecemeal. Another

option would be the range function.

The use of the individual functions was familiar only with the key combination, for which I thank you very much in retrospect, and of course also for the help.
