Little help with circles/curves in BASIC

[skylas]

Hi,
I am trying to make some circle shapes in BASIC, but I can only make typical circles following the original instructions manual.


My question is how i can make curve, similar to the sickle in the hammersickle symbol, or similar to the crescent moon symbol.

Any ideas? And what do I have to alternate in order to customize on my wish?

By learning some basic geometry: https://www.mathsisfun.com/geometry/circle.html and applying it in BASIC.

I did not study much geometry to totally understand what I am doing, but i made many tries by changing many things on Con and Sin and I think I managed to understand better what effect each change does.
