I greatly appreciate your time and help, Werner. Still have a very small query : How to add the base of the cup ?

Best Regards.

Just don't fill liquid in the cup 🙂

Now you can fill in liquid or trap a fly underneath 😉

Werner, I'm imagining I could fill in hot coffee now 🙂 and want keep it warm. And how to add the lid of the cup ?

You won't be able to access your coffee if you add the lid. But you can use the very same principle to add the tp surface as I did with the bottom (which gets the top if the height is negative, as you could see).

Simply map for example the interval from 1 to 2 for t to the range from r2 to 0 using another if statement in the definition of f(t). I'll leave it as an exercise for you to do 😉

But you sure could simply add a (slightly larger) lid as a separate cone of only marginal (negative) height:

Werner, follow your hint and do exercise, I guess now I could "trap a fly underneath" : 🙂
